There's no listitem for a dialog type MSGBOX

Instead use the code as like below

PHP код:

if(dialogid == DIALOG_DELETE_FURNITURE)
    {
        if(!response)
        {
                    // PRESSED NO.
            SendClientMessage(playerid, COLOR_LIGHTRED, "You cancelled deleting the furniture!");
            return 1;
        }
                 //PRESSED YES.
         DestroyDynamicObject(EDIT_OBJECT[playerid]);
         DestroyObject(EDIT_OBJECT[playerid]);
    }
