display iframe in spry collapsible panel

I have a spry collapsible panel that is defaulted closed. When the user clicks on the closed panel I want it to open and display a third party website inside of an iframe. The code I have works just fine outside of the collapsible panel. When I put it into the panel it does not work. This may need an on click javascript function to load the iframe into the open panel on click. However I am not sure. I will send you the code upon request.
