Ah, yes. I took out some classes that were for animating after the button click, and now the "button click" works. It also trimmed down the file size quite a bit, so that's an added bonus.
What's strange now, is that when the button is clicked, two text fields are updated. The movie is being published as Flash 7, so that's not it. I've even traced where the asset was being hosted on chumby.com, and it works in my browser. My fonts are also embedded, so that makes me even more confused. Does anyone know of why something would prevent my text fields from being populated when the button is clicked? For help, here's the code doing the work. In this case, this.id equates to the id stored for the thumbnail being clicked on (either 0, 1, or 2). Again, it works outside of the chumby, so I'm lost.
container["thumb" + i].onRelease = function():Void
container.attachMovie("titleOverlay", "titleOverlay", container.getNextHighestDepth()); //attaches the overlay with the text fields
titleOverlay.titleText.text = titlesArray[this.id]; //sets the text - works in a browser and locally
titleOverlay.descriptionText.text = descriptionArray[this.id]; //sets the text - works in a browser and locally
titleOverlay.overlayLayer.onRelease = function():Void //when the background is clicked, remove the movie clip
titleOverlay.closeButton.onRelease = titleOverlay.overlayLayer.onRelease; //when the close button is clicked, remove the movie clip
