Or if you are using javascript and you want to have a button in one frame that calls form items in another frame it would look something like this:
parent.child_name.form_name.form_item.value;
You go back up one to parent, then down to the child frame you want, and then to the form name, etc... If my syntax is not exactly correct for both browsers, go over to
www.javascript.com and do a search for parent and frames.
Hope that helps,
