¶1Thjs is an action by appellant against appellee to recover judgment for an amount alleged to be due as a commission for the exchange of certain real estate. The complaint is in a single paragraph and alleges in substance, among other things, that the parties on February 18, 1916, entered into a written agreement, by the terms of which appellee employed appellant to find a purchaser for certain real estate owned by him within a specified time and at a price named in a memorandum on the reverse side of said contract; that said contract provided that:
“In the event said real estate is sold by you during said time for said price, and upon said terms, or for a price and upon terms acceptable to me, then and in either of said events, in consideration of your services in this connection, I promise and agree to pay you the regular fixed commission as *6adopted by the Fort Wayne Real Estate Exchange, or in the event said real estate is traded or exchanged by or through your efforts I promise and agree to pay you such commission on the list price fixed in said memorandum. Complete abstract showing good title to said property and warranty deed will be furnished by me. Less expense Zane put to in making the exchange.”
¶2That the list price fixed in said memorandum was $30,000, and appellant, within the time specified, made an exchange of said real* estate; that at the time of the execution of said written agreement there was, and ever since has been, in existence in the city of Fort Wayne, Indiana, an association of the real estate men of that city and surrounding territory known as the Fort Wayne Real Estate Exchange of Fort Wayne, Indiana; that, prior to the date of said contract, said exchange had adopted as the regular fixed commission for the sale or exchange of farm property the rate of five per cent., which adoption was made by a resolution of said exchange, duly entered in its minutes; that said resolution was in full force and effect at the time said contract was executed, and has so remained ever since; that it was said rate so adopted that was intended and referred to in said contract, a copy of which contract, including said memorandum, was filed with the complaint as an exhibit. To this complaint appellee filed a demurrer, which was overruled. He then -filed an answer in two paragraphs, the first being a general denial. The second paragraph admits the execution of the contract in suit, and alleges facts by which he seeks to limit the rate of commission thereunder to .two and one-half per cent, of the list price of the real estate mentioned therein. To this paragraph of answer appellant filed a demurrer, which was overruled. He then filed a 'reply thereto in general denial. Appellee also filed a counterclaim against appellant, to which a demurrer was sustained. *7The cause was submitted to a jury for trial, and at the close of appellant’s evidence the court instructed the jury to return a verdict for appellee, which was accordingly done. Appellant filecl a motion for a new trial, which was overruled, and judgment was thereupon rendered against him for costs. He now prosecutes this appeal under an assignment of errors, which requires a consideration of the question hereinafter determined.
¶3The only error presented by appellant in his propositions and points is based on the: action of the court in overruling his motion for a new trial. One of the reasons assigned therefor is that the court erred in striking from the evidence a certain paper, which had been introduced as exhibit “B,” and which is in part as follows-:
“Minutes- of the meeting of the Ft. Wayne Real Estate Exchange, held Tuesday, May 13, 1913. The Fort Wayne Real Estate Exchange met at the Anthony Hotel, Tuesday noon, May 13, 1913, … committee on commissions recommended a minimum commission of Five ($5.00) Dollars per acre for handling farm lands, and five per cent, of the sale price wherever the ground sold for more than $100.00 per acre, and this commission was adopted by the Exchange as standard.”
¶4These minutes were duly attested by the names of persons subscribing themselves as president and secretary. The record discloses that, prior to the introduction of said exhibit in evidence, one Hilgemann had testified in substance that there was an organization in the city of Fort Wayne known as the Fort Wayne Real Estate Exchange, and that it had been in existence since the spring of 1913; that he ha'd been its secretary for the last two years, and had in his' charge the minute book of said organization, which he then had in his hands; that a certain page thereof, marked exhibit “B,” and to which his attention was directed, contained the *8minutes of said organization, held on May 13, 1913. Said exhibit was then admitted and read in evidence over appellee’s- objections. Appellee then moved the court to strike out said exhibit, which motion was sustained over the objections of appellant. It is contended by appellant that this ruling of the court constitutes reversible error.

¶7But it will be noted, as stated above, that appellee makes the further contention that said exhibit “B” shows that the rate adopted by said exchange was a mini*10mum rate only, and hence any, rate in excess of said minimum rate might be proved; that this fact would render said contract ineffective under §7463 Burns 1914, supra, as it would leave uncertain one element of such contract, which the statute requires must be certain. This contention is not tenable. It will be observed that the contract recites that “in consideration of your services in this connection, I promise and agree to pay you the regular fixed commission, as adopted by the Fort Wayne Real Estate Exchange.” (Our italics.) By reference to said exhibit “B,” which contains the minutes of said exchange in that regard, we note that only one regular commission was fixed by said exchange, and that was a minimum of $5 per acre, except where land sold for more than $100 per acre, in which event the .commission should be five per cent, of the sale price, and that the commission thus fixed was adopted by the exchange as standard. It does not appear that the exchange attempted to fix any other schedule or rate of commission, but was content to adopt the minimum rate specified and declare it to be the standard rate. In view of these facts, we are forced to conclude that the minutes of said exchange, as evidenced by said exhibit “B,” furnished definite means of ascertaining the rate of commission to which appellant was entitled, and that the court erred in striking out the same after it had been introduced in evidence. To hold otherwise would have the effect of nullifying the contract in suit, which we would be reluctant to do after it has been executed and appellee has received the fruits thereof.

¶10For the reason stated the judgment is reversed, with instructions to sustain appellant’s motion for a new trial, and for further proceedings consistent with this opinion. , '
