As breet7 said, you should change loggedin[playerid] to the variable u are using. Anyways, I think u are using this "logged[playerid]" variable from lookning at bogeyman_EST's tutorial.

pawn Код:

public OnPlayerRequestSpawn(playerid)
{
    if(logged[playerid] == 0) return SendClientMessage(playerid, 0xFF0000AA, "you must login");
    return 1;
}

Good Luck.
