[Crystallize]

PHP код:

switch(strval(text))//Switch through the number they type in. 
        { 
            case 1: GivePlayerWeapon(playerid,22,50);//Give the player the weapon they typed the option for 
            SendClientMessage(playerid, green,"You have purchased 9mm for $2,500");
            GivePlayerMoney(playerid, -2500);
        } 


Didn't test it , but it should work
