redirect with CGI

hi,

my site is hosted by freewebspace.com, who don't allow CGI uploads but they have a decent CGI section. I've adapted / used one of their forms in my site and have managed to redirect the email to my preferred email addy.

However, I want the site to display a 'thankyou' page instead of the status page after a submission. Freewebspace.com say the tag should be:

Filename is file you want to be displayed after send button is hit. They say this has to be relative path so data can be shared with this file, (if you want to display the users name in the thankyou screen for example). All my files are stored at root, enquiry form is at:

http://webworksrus.freewebspace.com/enquiryform.htm

thankyou page is at:

http://webworksrus.freewebspace.com/thankyou.htm

I've tried the above hidden tag using both relative and absolute paths in the value part but neither works. The form still sends but I still get the stats page showing. Any suggestions as to why it ain't working? Why is my thankyou page not appearing? Any help would be much appreciated.
