apple iweb embedding problems

This is my form which works fine

http://creator.zoho.com/imaginate/online-donation-form/form/1/

except when I embed it in an iweb website... it doesn't upload the use information. Why?

Here is the link to the location where its not working.

Can you tell me why its not working here?
