[Private200]

Well, you can use something like this:

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;
}

And after writing that somewhere on your script, you go over the 'OnPlayerText' or wherever you want to use it and do this:

pawn Code:

format(string, sizeof(string), "[%s]: %s *[%s]*", atext, PlayerName(i), AdminDuty);
SendClientMessage(playerid, COLOR_WHITE, string);

This shall be fine.

Tell me if it works or either not.

EDIT: I saw this '[%s]: %s *[%s]*, atext', you're using text before name, are you sure about that? It's going to be like "Hello server: Private200 *[OnDuty]*". Change the places to fix it like this:

pawn Code:

format(string, sizeof(string), "[%s]: %s *[%s]*", PlayerName(i), atext, AdminDuty);
SendClientMessage(playerid, COLOR_WHITE, string);
