HTML Forms

I have several HTML forms that I have been using on our Company’s intranet sites to email information between different groups. The data submitted on the forms worked in Notes 6.0, but we upgrade to Notes 6.5.1 and now the information does not display in the email body. Occasionally it is placed in the “To:” box on the email. Is this an HTML problem or do I need to make changes to the preferences in Notes.
