Ok check the code u originally posted. Ur missing a close bracket That's all that's wrong

EDIT - Actually ur code is really not making any sense…here...

pawn Код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if(dialogid == 16) {
        if(response) {
            switch(listitem) {
                case 0: GivePlayerWeapon(playerid, 24, 500);
                case 1: GivePlayerWeapon(playerid, 27, 500);
                case 2: GivePlayerWeapon(playerid, 31,500);
            }
        }
    }
    return 1;
}

that's how the code should look.
