            else SetPlayerHealth(playerid, 100); //Prevents health going above 100.  If you want to enable  this, remove this line and the if statement above.
        }
        else return SendClientMessage(playerid, -1, "You must die first before you can heal again!");
    }
    else return SendClientMessage(playerid, -1, "You are not a medic!");
}
