Try putting this in a stock:

pawn Код:

{
            RemovePlayerFromVehicle(playerid);
            TogglePlayerControllable(playerid, 1);
            SendClientMessage(playerid, COLOR_WHITE, "{F20000}GRESKA:{FFFFFF} Nemate dovolno pari.");
            return 1;
        }

Then change the line to:

pawn Код:

if(!response) return stocknamehere(parameters);
//Other code here

Edit:Ignore that ^^ Sorry.

Place the if(!response) outside of your if(dialogid == KolaNaProdazba), like just under OnDialogResponse.
