You aren't setting the team on Request Class?

an example

pawn Код:

public OnPlayerRequestClass(playerid, classid)
{ 
    switch(classid)
    {
         case 0:
         {
               SetPlayerTeam(playerid, TEAM); // replace TEAM
         }
         case 1:
         {
               SetPlayerTeam(playerid, TEAM); // replace TEAM again...
         }
    }
    return 1;
}

I think you get the point. Your just setting the GameTextForPlayer and not giving the player a chance to set their team.
