It's hard to know exactly what's going on without looking at your files, but I think this is just a case of FrontPage adding some stuff and confusing you a bit. The script that we're talking about is a standard FrontPage script that is used for the menu buttons as I've mentioned before. It looks like you have used a template for your site and this is where the code came from. Again, it's standard FrontPage stuff. If you search for a line or function name of the code online, you'll find lots of other places where it can be found, all relating to FrontPage. (Note the acronym in the code - MSFP. It stands for Microsoft FrontPage).
If you think the code is being added by the server, then upload your version, wait a while, and download the file on the server. Compare the downloaded file with the local copy using a File Comparison tool like
WinMerge.
Again, it's hard to know exactly where the code is coming from without knowing your complete setup or having access to your computer, but the code
is safe and it's necessary for the template you are using. If you are concerned that FrontPage is adding code to your site behind the scenes, welcome to FrontPage. You might want to move to an editor that isn't 7 years old.
