Damage on collision problems...

I have this problem, I am trying to make a fire particle damage my player.

I have no clue what´s wrong every forum with people having the same problem make it work but when I use the same solution, nothing happens.

That´s the primary problem, not that it is too quick to damage or something like that, seriously nothing fucking happens.

This is the Damage on collision script (js) (tried to make it as basic as possible)

---

var damage = 10;

function OnCollisionEnter (collision : Collision)

{

collision.gameObject.SendMessageUpwards("PlayerDamage", damage); Debug.Log ("Collision entered");

}

and this is the my PlayerDamage script (All credit to Armed Unity)

/** Script written by OMA [www.armedunity.com] */

@script ExecuteInEditMode()

var hitPoints : float; var regenerationSkill : int; var shieldSkill : int; var painSound : AudioClip; var die : AudioClip; var deadReplacement : Transform; var mySkin : GUISkin; var explShake : GameObject; private var radar : GameObject; var maxHitPoints : int; var damageTexture : Texture; private var time : float = 0.0; private var alpha : float; private var callFunction : boolean = false; private var scoreManager : ScoreManager;

function Start(){ maxHitPoints = hitPoints; alpha = 0; }

function Update(){ if (time > 0){ time -= Time.deltaTime; } alpha = time; if( hitPoints <= maxHitPoints){ hitPoints += Time.deltaTime * regenerationSkill; }

 if( hitPoints > maxHitPoints){
     var convertToScore : float = hitPoints - maxHitPoints;
     scoreManager = gameObject.Find("ScoreManager").GetComponent("ScoreManager");
     scoreManager.addScore(convertToScore);
     hitPoints = maxHitPoints;
 }    

}

function PlayerDamage (damage : int) { if (hitPoints < 0.0) return;

 damage -= shieldSkill;
 
 if(damage > 0){
     // Apply damage
     hitPoints -= damage;
     audio.PlayOneShot(painSound, 1.0 / audio.volume);
     time = 2.0;        
 

     // Are we dead?
     if (hitPoints <= 0.0)
     Die();
 }else{
     damage = 0;
 }    

}

//Picking up MedicKit function Medic (medic : int){

 hitPoints += medic;
 
 if(hitPoints > maxHitPoints)
 hitPoints = maxHitPoints;

}

function Die () { if(callFunction) return; callFunction = true;

 if (die && deadReplacement)
     AudioSource.PlayClipAtPoint(die, transform.position);

 // Disable all script behaviours (Essentially deactivating player control)
 var coms : Component[] = GetComponentsInChildren(MonoBehaviour);
 for (var b in coms) {
     var p : MonoBehaviour = b as MonoBehaviour;
     if (p)
         p.enabled = false;
 }
 // Disable all renderers
 var gos = GetComponentsInChildren(Renderer);
 for( var go : Renderer in gos){
     go.enabled = false;

 }
 if(radar != null){
     radar = gameObject.FindWithTag("Radar");
     radar.gameObject.SetActive(false);
 }
 Instantiate(deadReplacement, transform.position, transform.rotation);
 yield WaitForSeconds(4.5);
 //Destroy (transform.root.gameObject);
 LevelLoadFade.FadeAndLoadLevel(Application.loadedLevel, Color.black, 2.0);

}

function OnGUI () { GUI.skin = mySkin; var style1 = mySkin.customStyles[0]; GUI.Label (Rect(40, Screen.height - 50,60,60)," Health: "); GUI.Label (Rect(100, Screen.height - 50,60,60),"" +hitPoints.ToString("F0"), style1);

 GUI.color = Color(1.0, 1.0, 1.0, alpha); //Color (r,g,b,a)
 GUI.DrawTexture(new Rect(0,0,Screen.width, Screen.height), damageTexture);

}

function Exploasion(){ explShake.animation.Play("exploasion"); }

I don´t know what is wrong and the console in unity doesn´t find any errors,

Hope someone can help me!
