Launching Multiple Pop Up Windows - HELP

I recently used the “Launching a Centered Pop Up Window” tutorial in an effort to make several Flash buttons that would launch several pop ups from one html page. The problem is, when the first pop up is launched and I return to the main html page without closing the pop up, I am not able to refresh the pop up window when another flash button is clicked. The original content (url) of the first flash button remains. Only after closing the pop up window will the another flash button activate a new pop up window and display new content. And then the same problem occurs with the latest pop up. I’m sure this is a JavaScript issue, but I’m not real sure how to fix it.

Please Advise. Many thanks for your help.:nerd:
