I've looked through a bunch of the questions on here involving this but they don't answer in a way that seems logical for my use. So here it goes: (I've added in the script because I find it useful answering questions with it, though I don't think it may be necessary to answer this question)

Thanks for the look!

First the Hierarchy.
-Animations
o-Communicator
oo-Interaction

On the "Interaction" level I have a child object that I click/interact with and it triggers CS code called "UpButton". This code triggers a boolean value to be made true in a function "WasUpPressed":

    bool upPressed = false;

    void OnMouseDown()
    {
       upPressed = true;
    }

    bool WasUpPressed()
    {
       return upPressed;
    }

Now on the "Communicator" level I have a JS. This tells an animation to play on the "Animation" level if it "hears" that "WasUpPressed" returns true :

    var upbutton = false;

    function Update () 
    {   

         upbutton = GetComponent(UpButton);
         upbutton.WasUpPressed();

         if(upbutton)
         {
            transform.parent.gameObject.animation.Play("m-1");
         }
     }

To me it seems as if this would work, however, I can't even see if it does because it won't compile in the Project for me to be able to even attach it to my gameObject. The error I get is "Unknown Identifier: 'UpButton'" which will obviously be the case if the script isn't attached to the gameObject. So how do I fix this??
