Ah, I understand. In my case it would be:

pawn Код:

public OnPlayerRequestSpawn(playerid)
{
    if(gClass[playerid] == 0)
    {
        if(AlphaMembers > GammaMembers)
        {
            SendClientMessage(playerid,COLOR, "Team is full!");
            return 0;
        }
    }
    else if(gClass[playerid] == 1)
    {
        if(GammaMembers > AlphaMembers)
        {
            SendClientMessage(playerid,COLOR, "Team is full.");
            return 0;
        }
    }
    return 1;
}

By the way, I found this at Wiki:

Thanks all for help!
