Can someone explain to me why my invisible button isn't working?

My instance name for the button is: resume_btn
My label for my page is titled: resume
(The labels layer is above the pages layer and on the same frames. And all the capitalization is correct too)

When I go in to edit my button I have my hit state the one that has the rectangle in it. The rest of them have blank keyframes. When I preview it the button looks as if it would work but when you click it doesn't take you anywhere!

The actionscript I've used is this:
Code:
resume_btn.onRelease = function(){
	gotoAndStop("resume");
}
All of the script is set on its own layer.

What's wrong with it? Help!
