Save a Form from a popup box

I have a form with a save button that triggers a popup box from a different file. In the popup box I have a yes & no checkbox and a save or cancel button....I want to be able to save the form from the popup box how can I do this?:confused:

I'm assuming that when you say "save" the form your talking about submitting the form.

window.parent.document.forms[0].submit();

Obviously you'll have to edit this for your site.

hope this helps....
