How to override in javascript?

Hi all, I need to be able to override a variable in JS. In this case it is a string variable. Basically, I have a script that generates an item and gives it a random name based on an array of strings. However, in a seperate script where I have the item variables defined eg: name, value, rarity; I get an ambiguous reference error. I am assuming this is because unity doesn't know whether to use the name I assigned, or the randomly generated name from the string array. If someone could give me a small example of how to do an override in JS i'm sure I could figure the rest out on my own.

Thank you and sorry if this is confusing. If you need any more info or code just ask and I will provide.

Can you show us the relevant class declarations? I think I have an idea what's going on here, but I can't be sure unless I see the line that the error is occurring on.

 Item.js
 
 enum Rarity{Common, Uncommon, Rare, Beastly, Insane, Epic, Legendary}
 enum ArmorSlots {Head, Neck, Shoulders, Arms, Forearms, Hands, Torso, Waist, Legs, Feet}
 
 var name : String;
 var description : String;
 var rarity : Rarity;
 var curDura : int;
 var maxDura : int;
 var _value : int;
 
 var icon : Texture2D;    
 
 function Item() {
 
     name = "Name $$anonymous$$e";
     _value = 0;
     rarity = Rarity.Common;
     maxdura = 50;
     curDura = maxDura;
 }
 
  function ToolTip() { //public virtual string
 
          return name + "/n" +  <<<ERROR OCCURS HERE
 `            "Value" + _value + "/n" +
          "Durability" + curDura + "/" + maxDura + "/n";
 }

 ItemGenerator.js
 
 var item : Item;
 var WeaponScript;
 var _weapon;
 var temp;
 
 var BASE_$$anonymous$$ELEE_RANGE : int = 1;
 var BASE_RANGED_RANGE : int = 5;
 
 var $$anonymous$$ELEE_WEAPON_PATH : String = "Item Icons/Weapon/$$anonymous$$elee/";
 var weaponNames : String[];
 
 function Start() {
 }
 
 function Update () {
 }
 
 function CreateItem() {  
  
 //CreateWeapon();
 //Decide what type of item to make
 //Call the method to create that base item type
 item = CreateWeapon();
 
 //private string _name;
 item._value = Random.Range(1, 101);
 item.rarity = Rarity.Common;
 item.maxDura = Random.Range(50, 61);
 item.curDura = item.maxDurab;
 
 return item;
 }
 
 function CreateWeapon() {
 //Decide if we make a melee or ranged weapon
 _weapon = Create$$anonymous$$eleeWeapon();
 
 //Return the weapon created
 return _weapon;
 }
 
 function Create$$anonymous$$eleeWeapon() {
 _weapon = new WeaponScript();
 
 weaponNames = new String[3];
 weaponNames[0] = "Short Sword";
 weaponNames[1] = "$$anonymous$$orningstar";
 weaponNames[2] = "Silifi";
 
 //Fill in all of the values for that item type
 _weapon.name = weaponNames[Random.Range(0,weaponNames.Length)];
 
 //Assign the max damage of the weapon
 _weapon.maxDamage = Random.Range(5,11);
 //_weapon.DamageVariance = Random.Range(.2f, .76f);
 _weapon.dmgType = DamageType.Slash;
 
 _weapon.maxRange = BASE_$$anonymous$$ELEE_RANGE;
 
 //Assign the icon for the weapon
 _weapon.Icon = Resources.Load($$anonymous$$ELEE_WEAPON_PATH + _weapon.Name) as Texture2D;
 
 return _weapon;
 }
 
 enum ItemType { Armor, Weapon, Potion, Scroll }

That's the Item.js and ItemGenerator.js scripts. I marked the line in Item.js where the error occurs.

Just a wild guess, shouldn't it be "backslash n" if you want a new line? (can't write it here)

You shouldn't be using the constructor for components. Where you have the constructor, you should use Awake() and AddComponent(typename). I'm actually not sure if that's exactly what's causing the problem, but it's an issue waiting to happen.
