>>I would like to be able to insert <%= somename.html %> into the FWX file and have it get processed just as though the HTML was actually in the FWX file. Then I could create the data entry forms with an HTML editor and use it in my FWX file without having to physically move it from one file to the other.<<
If I understand your request correctly, you can already do this. Why not just edit the .fwx file with your HTML editor? I do this with Dreamweaver and my favourite text editor (TextPad) all the time. After all, the .fwx file is just a HTML file with a few %% tags inserted. Most HTML editors will take files of any extension, not just .htm or .html)
