iframe problem

I need some help white my iframe page.

I have a page whit a menu and a iframe in it. When some one click on the menu a page is loaded into the iframe. Thats no problem.

In the menu there is a button to send the page into iframe by e-mail out of extarnal window. The script is looking true document.all. oIFRame.src whitch page is loaded. No problem.

But when there is into the loaded page a second link and it is folowed document.all. oIFRame.src wil return the last menu click and not hte curent page loaded into the iframe.

Question: How can a real check the page into the iframe?

Thanks inadvance
