var mainmenuSkin : GUISkin;

function OnGUI () { GUI.skin = mainmenuSkin;

var ScreenX : int = 10;
var ScreenY : int = 10;
var areaWidth : int = 100;
var areaHeight : int = 100; 

GUILayout.BeginArea (Rect (ScreenX, ScreenY, areaWidth, areaHeight));

if(GUILayout.Button ("MoveCube")){

} GUILayout.EndArea(); }

Once i add:

animation.Play(GuiCubeMove.anim);

after the:

if(GUILayout.Button("MoveCube"))

I receive a "unknown identifier" error. Double checked the animation name to GuiCubeMove.anim, and tried removing the file extension...totally new to scripting.

That didn't work...let me repost as an answer.

The animation needs to be a component of the same GameObject where your GUI script is attached to. If it is not, and it's not possible for you to restructure the scene accordingly, you first need to find the animated GameObject (or assign it in the Inspector using a public var) first, and then start its animation with something like myAnimatedGameObject.animation.Play("GuiCubeMove"); (you probably don't want to add the file extension .anim, unless the name of your animation also contains that extension when you look at the Animatino component of that object in the Inspector.

OH! Attaching the GUI to my animated object worked perfectly, and brought about yet another "well duh" moment between myself and Unity.

I understand the concept of the public variable, not sure how to execute it though...might have to make that another question for later. THANKS!

If you declare a public variable in a script, it will show up in the Inspector when you attach that script to an object. Then you can modify the default value for that variable in the Inspector, without touching the script. This varibal can be anything from a simple int/float number, or even a whole GameObject.
