Passing variables via URL

ok, i posted something like this earlier adn then thought it fixed itself. turns out it didn’t.
i have a movie that loads in swfs based on a variable “pID”. this works just fine, BUT for some reason it works in two different ways if you just type in the url or COPY PASTE s3iz.com/2004/index.php?pID=23 it works great the site functions like it’s supposed to.(when you go down to the bars at the bottom a menu should come up and the flash movie should pause). NOW try clicking on a link to the same page.
http://www.s3iz.com/2004/index.php?pID=23 (now the menu doesn’t pause the swf and you can’t load in new swfs from the menu. WTF
also. if you load in just a jpg by clicking this link http://s3iz.com/2004/index.php?pID=16 you have the same problem but now you can load in other swfs but they still don’t pause.

if anyone has any ideas i would be most happy, i know it’s hard to determine problems like this with out viewing any code.

thanks
