Automating html wizard

Hi:
Back for another note on using the html wizard. When going into the wizard to set up all the parameters for the html page, I am able to do everything properly and completely, getting a nice looking statistical page for school records, team schedule and other data I have.

However, when I want to export the html page, the file generated in the wizard is a .txt file instead of an .html file. I was wondering if that was just an oversight in the underlying coding. I can manually change the name easily enough, but thought that I would point this out just as an observation. I was thinking that once you select the html box in the wizard, it would know to generate an .html file rather than a .txt file
