I have a form on a page which has some feild values feed to it from an IFrame
using Javascript - if the user interacts with the IFrame.

When I submit the form without interacting with the Iframe, all fields and
values are submitted.

If I submit the form having used the IFrame to populate some fields, no fields
are submitted.

I have tried setting the focus back to a form field after the IFrame is used
- this makes no difference.

Thanks in advance for any help you might provide.
