Or you could use a switch, a bit better

And you must "return 0;" at the end

pawn Код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    switch(dialogid)
    {
        case 0:
        {
             //Dialog components
        }
        case 1:
    }
    return 0;
}
