[Private200]

pawn Code:

stock AdminDuty(playerid)
{
    new AdminDuty[32];
    if(PlayerInfo[playerid][pAdminDuty] == 0) format(AdminDuty, sizeof(AdminDuty), "OffDuty");
    else if(PlayerInfo[playerid][pAdminDuty] == 1) format(AdminDuty, sizeof(AdminDuty), "OnDuty/ReadyToHelp");
    return AdminDuty;
}

Change the old stock to this one, and it shall work fine.
