there are brackets missing...
use this:

pawn Код:

public OnPlayerConnect(playerid)
{

    new plname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, plname, sizeof(plname));
    if(Security != 0)
    {
        SendClientMessage(playerid, COLOR_YELLOW, "Host has broken one of the Agreement rules, action has been taken.");
        Kick(playerid);
        return 1;
    }
    return 1;
}
