desparate woman here - forms not working!

[W E B G U R L]

I asked months back without any help and I need to alter my forms and
cannot.

I go to design view to make changes then publish my form. Open in Outlook
and instead of being HTML, it opens as plain text. Yes, I do have HTML
selected in my options.

Am I the only person this has happened to? There must be a solution!

Any help is truly appreciated.
