error BCE0022: Cannot convert error, please help

Hello all,

I'm relatively new to Unity & could use some help. I'll try to be as specific & concise as possible...

I have a pathNode.js script that has the following:

 enum PathInstruction{moveLeft=0, moveRight=1, moveStop=2, jumpAir=3}

 var pathInstruction = PathInstruction.moveStop;    

 function OnTriggerEnter (other : Collider)
 {

     if(other.tag == "enemy")

     {
         print("Goomba's here");
     }
 }

On a separate enemyGumba.js, I am trying to call pathInstruction & assign it to my gumbaState with the following lines:

 /*variables*/
 enum GumbaState{moveLeft=0, moveRight=1, moveStop=2, jumpAir=3, enemyDie=4, goHome=5}
 /*basic movements*/
 var gumbaState = GumbaState.moveLeft;
 :
 :
 function OnTriggerEnter (other : Collider)
 {
     /*when gumba collides with pathNode*/
     if(other.tag == "pathNode")
     {
         print(gumbaState);
         var linkToPathNode = other.GetComponent(pathNode);
         
         gumbaState = linkToPathNode.pathInstruction;
     }
 }

but- I am getting the error: BCE0022: Cannot convert 'PathInstruction' to 'GumbaState'. What can I do to correct this, do I need to instantiate gumbaState in a Start function?

Thanks in advance, scr33ner
