sorry to post twice but it has been 2 days, this is a timely issue.

IE8 gives the following warning when loading an https form:

Do you want to view only the webpage content that was delivered securely?

This webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the security of the entire webpage.

This will scare away some people from entering info, and perhaps it isn't secure.  I need https because I am having students input personal data.  Is there anything I can do about this?
