no i don't think you understand how it works.

HTML page containing form.
Visitor types in info
Submits form
Goes to script on server for processing.

that is what happens.

to get it to go to two different scripts for processing (what we want) is impossible directly (it appears). So what we do is get one of the scripts, to call the other script not as a form but using a URL. This is what ed suggests. The url will have to be done in a special way as shown to make it work. Everyone net probably won't allow their scripts to sign people up in this way (GET as opposed to POST) but you can try.
