In an action for broker's commissions, an instruction that "merely procuring a purchaser to enter into a contract for the purchase of property does not entitle a broker to commissions, unless such persons are ready, willing and able to make the payments * * * named in the contract," was properly modified by adding, "unless the seller accepted the purchaser." Fox v. Ryan, 240 I11. 391, 88 N. E. 974. See Sec. 24.
