Can you access an HTML object from the last page?

Can you access an HTML object from the last HTML page if you know the ElementId?

I am processing a form using ASP, but I'd like to access other elements from the form page that are not form items. (The page is dynamically created so there's information on it I can't anticipate)

I tried....

parent.document.getElementById('UserID').innerHTML

But, to my surprise, there's no parent. I'll explain, if I use alert(parent.location.href) I get the href of the ASP page not the Form page that launched the ASP page ?!

An ideas.....

Many thanks,
Peter
