I'd like to set up the ability to provide feedback on pages on one of my websites. This would entail passing a parameter (URL location of the page the user is providing feedback about) to a Zoho Form.

What I would like is the following behaviour.

1)User clicks "Feedback" link on the given page. 

2) The link calls another page with an embedded (via IFRAME) Zoho Creator feedback capture page (form).

One of the fields on the Zoho form is the site URL. This field is automatically populated based on the paramater passed from the "Feedback" link.

3) User fills out other fields manually and hits submit.

4) Upon submition, user gets returned to a thank you page with an option to return to the original page (prior to clicking the "Feedback" link).

Any ideas on how to do this?
