All the answers are on my website to tell you all the things you are doing
wrong. You don't need an IT background, it's assumed you are here because
you are a newbie. All I ask is that you read the ample material I provide.
From your updated post it appears you need to start with the basics of how
to correctly upload the web site. That info is on the sites web design, 2003
section. The publish in http article is the one you need. You then need to
read thru all the form subject Q and A on the web design FAQ page. They
explain the fundamental requirements of using a Publisher form.
As for the ISP program, it won't work unless you program the ISP program to
work with the form fields. Something that is by your admission beyond your
skill set. So you need to stick with Publishers form processing.
