BroadcastMessage frustratng problem

Hi guys, I've spent the last four days on this and it has consumed me every waking second.

I'm working in FPS KIT 2. All I'm looking to do is to give a player a gun once he reaches a certain amount of kills. I'm able to pull the kills from the server, play a sound, etc. But trying to actually give him the gun is quite the challenge!

I've tried sendmessage, broadcastmessage, getcomponent, getcomponentsinchildren. Here's the gist of it;

 UpgradeLine.CS
 public AudioClip UpgradeSound;
     bool upgraded;
     int prevKills = 0;
     GameObject player = GameObject.FindGameObjectWithTag("Player");//Find local player
     string[] upgradeTemplate = new string[10];
     public GameObject upgrade3;
 
 
    void Update () {
         upgraded = (bool)PhotonNetwork.player.customProperties["Upgraded"];//Get weather we have been upgraded from the server
         upgradeLine((int)PhotonNetwork.player.customProperties["Kills"]);//I have no idea what i'm doing so I"m pulling kills from the server and hoping
     }
 
      void upgradeLine(int kills){
             if(upgraded == false){ //Don't do anything unless we haven't been upgraded yet
                 if(kills == 3 && kills != prevKills){ //Kill three
                             BroadcastMessage("addUpgradedGun", upgrade3);
                             upgraded = true;//Okay, we've been upgraded
                             Hashtable setPlayerUpgraded = new Hashtable() {{"Upgraded", upgraded}};//Tell server we've been upgraded
                             PhotonNetwork.player.SetCustomProperties(setPlayerUpgraded);
                             prevKills = kills;
                             audio.clip = UpgradeSound;//play sound
                             audio.Play();
                     }
                 } else {
                     upgraded = false;
                 }

And then here's the receiver, which is located on the same gameobject, not a child:

 WeaponPickUp.js
 public function AddUpgradedGun(gunAdd : WeaponScript){
             weapManager.allWeapons.Add(gunAdd);
             weapManager.SwitchWeapons(weapManager.SelectedWeapon.gameObject, weapManager.allWeapons[weapManager.allWeapons.Count-1].gameObject);
             weapManager.index = weapManager.allWeapons.Count-1;
             //Register Action
              actionsList.Add(("Picked | " + gunAdd.weaponName).ToString());
 }

I've tried placing the JS files in a folder called Standard Assets, I've also tried it the other way around with the CS files. Here's the error with this exact code:

 BroadcastMessage addUpgradedGun has no receiver!
 UnityEngine.Component:BroadcastMessage(String, Object)
 UpgradeLine:upgradeLine(Int32) (at Assets/FPS Kit Version 2.0/_CustomAssets/Scripts/Network C#/UpgradeLine.cs:49)
 UpgradeLine:Update() (at Assets/FPS Kit Version 2.0/_CustomAssets/Scripts/Network C#/UpgradeLine.cs:39)

Using the same thing with getComponent and declaring private WeaponPickUp weapPickUp, It won't even let me compile, stating:

 error CS0246: The type or namespace name `WeaponPickUp' could not be found. Are you missing a using directive or an assembly reference?
