For loop not working?

I am trying to make a script that will add and edit hinge joints to every object in the scene with the tag "force". I have rewritten this script multiple times, and now it has stopped working completely. Here is the code-

 var forces : GameObject[];
 function Update () {
     forces = GameObject.FindGameObjectsWithTag("force");
     if(Input.GetKeyDown("l")) {
         Gotoedit ();
     }
 }
 
 function Gotoedit () {
     for(var i = 0; !i == forces.length; i++){
         GameObject.FindGameObjectWithTag("fuse").AddComponent(Rigidbody);
         forces[i].AddComponent(Rigidbody);
         forces[i].AddComponent(HingeJoint);
         forces[i].GetComponent(HingeJoint).connectedBody = GameObject.FindGameObjectWithTag("fuse").rigidbody;
         forces[i].GetComponent(HingeJoint).spring.damper = Mathf.Infinity;
     }
 }

I moved all the forces[i] statements to the function Update (), and them it worked fine with one GameObject, so I know it't not the AddComponent/GetComponent. I tried adding a debug in the Gotoedit, so I know that it is being called when I press the L key. This leaves the FOR statement, which i'm assuming is the problem. I'm fairly new to FOR statements (not javascript), so I came here to get advice. Does anyone have ideas?

*Javascript only, duh

*Thanks!
