need help accessing Filemaker through web form...

Sorry for posting this under General Discussion, but I wasn't sure where to put it.

About 2 years ago, someone created a Filemaker database for me using FMPro v5. It was set up so that I could access it across the network at my office using a web browser. The web pages were generated using HTML files titled "default", "error", and "results".

Now I'm trying to get this same database working in the same manner using FMPro v7.0 on my own, and I'm running into problems. I've managed turn on Instant Web Publishing and have successfully accessed it across the network. But this doesn't seem to be what I need, since it displays the data in a Filemaker-esque view instead of the HTML that I want.

I've also opened "default.htm" file across the network, which is how I've always accessed the web interface in the past. It opens fine, but when I do a search, the browser gives me a "page not found" error because it can't find "FMPro" in the same path where my HTML files are. Looking at the HTML in default.htm, I see the following line:

<FORM ACTION="FMPro" METHOD="post">

What is this FMPro supposed to be pointing to? Do I need to define Filemaker in my system paths or something? Do I have my directory structure set up wrong? Do I need to turn on some kind of server function in Filemaker for it to be accessible by the web page? Do I need Filemaker Server instead of just Pro?

Thanks and sorry for all the newbie questions!
