Hi Mark Raven:
Thanks for posting.
Some script steps are not compatible with web publishing. The script steps to import records, export records, or insert a picture are not web publishing compatible. The script steps supported for web publishing can be found at http://help.filemaker.com/app/answers/detail/a_id/6474. Your users can still run these scripts from FileMaker Pro though.
I encourage you to enter this suggestion into our Feature Requests web form at http://www.filemaker.com/company/contact/feature_request.html. I could easily copy your post and paste it into the web form, but there are personal questions asked that only you can answer.
