Document in Frame (Framset)

I have a frameset.

One frame is called “Menu.”

Another frame is called “Document.”

A form is set to always launch in the frameset.

How do I make the script in the Menu frame work with the document in the Document frame?

I’m kinda just toying around with things for now, but I’m wondering if this is even possible without having to write loads of script for each command (in order to reference the document).

I haven’t worked a lot with framesets in the past, so even if someone can point me in the write direction would be immensely helpful.

Thanks in advance!

Subject: To simplify this…

Let me see if I can make the example even more basic:

I have a button in the “Menu” frame that when clicked should update the field “TestField_1” on the form “TestForm” to “Yes.” The form is displayed/launched in the “Application” frame of the same frameset.

My first instict would be to use JavaScript. In avaScript it’s easy to address a field in another frame and it should work just fine in the Notes client.
