I will acknowledge that I am not an expert when it comes to forms or FPSE,
but I do have a couple suggestions, if you don't mind.

It sounds like you are saying that you have been using FTP to upload your
Publisher web files to your subfolder on your host, and it hasn't hurt the
main site. If you want to just continue to use FTP uploading then consider
using a simple javascript form instead of the Publisher form. It will be a
lot faster and easier than getting your Pub form to work. Here is one
example....just copy and paste the following into a code fragment box,
change the email address, do a web page preview and try it.

---------------

<FORM action=mailto:yourname@yourdomain.com method="post"
enctype="text/plain">
<TABLE BORDER="0" CELLSPACING="0" CELLPADDING="4" WIDTH="90%">
<TR>
<TD width="30%"><DIV align="right">
<B>Name:</B>
</DIV>
</TD>
<TD width="70%">
<INPUT type="text" name="name" size="20">
</TD>
</TR>
<TR>
<TD><DIV align="right"><B>Email:</B></DIV>
</TD>
<TD>
<INPUT type="text" name="email" size="20">
</TD>
</TR>
<TR>
<TD><DIV align="right">
<B>Comment:</B>
</DIV>
</TD>
<TD><TEXTAREA name="comment" cols="30" wrap="virtual" rows="4">
</TEXTAREA>
</TD></TR>
<TR>
<TD>&nbsp;</TD>
<TD>
<INPUT type="submit" name="submit" value="Submit">
<INPUT type="reset" name="reset" value="Reset">
</TD></TR>
</TABLE>
</FORM>

----------------

The form is more basic than the one you are using, but you can put a text
box above the form and ask people to tell you what group they are in, in the
comments section, if that information is that important. The main point is
by using a javascript based form you can avoid the hassle and time involved
in using the Pub built form and FPSE, and lessen the risk that you might
somehow mess up the main site by trying to use HTTP uploading instead of
FTP.

If the form is too basic for you, there are lots of other javascript forms
scripts available on the Web...just google for them. Also take the time to
go to your webhost and find out what forms program do they support. Mine
even gives me instructions and the code that I need to insert via a code
fragment box in a Pub page. You can use a different server side program with
the Publisher form objects. There are lots of alternatives to FPSE forms,
and personally I think most people would be wise to start moving to
something different and away from FPSE...for lots of reasons.

In your case, a simple javascript form may be enough...just some things to
think about.

You "can" use both if you know what NOT to touch...so it's just easier to
say don't touch that or  you'll break it!

folder is just a folder
subweb is an entity unto itself (a child web)
