I noticed you were missing a bracket.

pawn Код:

//The function below is called every 250ms
public HealthCheck()
{
    for(new i=0; i<MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i) && GetPlayerState(i) != PLAYER_STATE_SPECTATING && GetPlayerState(i) != PLAYER_STATE_WASTED)
        {
            new Float:health;
            GetPlayerHealth(i, health);
            if(health >= 100.0)
            {
                SetPlayerHealth(i, 75.0);
                GetPlayerHealth(i, health);
                if(health > 75.0)
                {
                    SendClientMessage(i, COLOR_RED, "-> Cheater");
                }
                else
                {
                    SendClientMessage(i, COLOR_RED, "-> Clean");
                    SetPlayerHealth(i, 100.0);
                }
            }
        }
    }
}

See if that helps?
