Object Not Dying

Hi Everybody,

I am sorry if this is a stupid question, I am new to Unity and trying to learn from some tutorials, etc. I have looked around for help before asking, and was not able to find anything.

I am trying to make a fps and am just building things up slowly. I am trying to make an object disappear when it gets show and its health reaches 0 or less.

The code if have for the gun is:

 var DamageAmount : int = 5;
 var TargetDistance : float;
 var AllowedRange : float = 15;
 
 function Update () {
     if(Input.GetButtonDown("Fire1")) {
 
         var Shot : RaycastHit;
             if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), Shot)) {
                 TargetDistance = Shot.distance;
                     if (TargetDistance < AllowedRange) {
                         Shot.transform.SendMessage("DeductHealth", DamageAmount, SendMessageOptions.DontRequireReceiver);
                     }
             }
     }
 }

and The code of I have the object that should disappear is

 var EnemyHealth : int = 10;
 
 function DeductHealth (DamageAmount : int) {
     EnemyHealth -= DamageAmount;
 }
 
 function Update () {
     if (EnemyHealth <= 0) {
     Destroy(gameObject);
     }
 }

My understanding is the first gun shot that hits the target and is within the range of 15 should take thier health down to 5, the second one should take it to 0 which should trigger the 'destroy(gameObject)'.

Nothing seems to happen at all when I shoot. If I have the GunMechanics selected (located under FirstPersonCharacter) on the Inspector, I can see the 'Target Distance' value change so the shot is being acknowledged at least in part.

If you need any more informaiton to answer, please let me know.

Thanks in Advance.
