var damage : int = 20;
function OnGUI () {
        if (curHp > 0) {
                GUI.DrawTexture(Rect((Screen.width/2) - 500, 10, hpBarLength, 10), HpBarTexture);
        }
        if (curMana > 0) {
                GUI.DrawTexture(Rect((Screen.width/2) - 500, 20, manaBarLength, 10), ManaBarTexture);
        }
}
function Update () {
        percentOfHP = curHp/maxHp;
        hpBarLength = percentOfHP*100;
        percentOfMana = curMana/maxMana;
        manaBarLength = percentOfMana*100;
        if(Input.GetKeyDown("h")) {
                curHp -= 10.0;
        }
        if(Input.GetKeyDown("m")) {
                curMana -= 10.0;
         
        if(collision.collider.tag == "Enemy")
                curHp = curHp - damage; 
        }

You need to move that collision check to a OnCollisionEnter function, not in your Update function.
