Problem with dynamic iframe

[Bsteph]

Hi
Im using this script http://www.dynamicdrive.com/dynamici...iframessi2.htm and when I load a page from the index site theres no problem with showing in the iframe. But however if i try to load a page from the page displayed in the iframe, then it wont do anything. Is there a simple solution to this, maybe a bit of script that should be added somewhere ? Can someone please help me

Regards
Bo
