Arghhh

Extremely frustrated to nite with our ISP- I guess we either need to switch from Ipower or learn HTML. All I am trying to do is add some Pay Pal shopping carts. Ipower tells me that to do that I need to upload the shopping carts via File manager and then just hyper link to them. WHAT?? first of all do I Upload the shopping carts as .docs. or text files or what? and then I can understand how to set up a hyperlink but a link to just a document?? how is the shopping cart going to show up?? I am so confused right now,,,  oh and I have talked with at least five different people from Tech support since Saturday and this evenings Mr helper (or I should say Mrs. Helper) finally told me that you cannot publish the HTML code through the cheapass web design program (CM4all) and remember I am paying for what is called the e-commerce version.... any ideas out there people? All I want to do is let people buy stuff from my website...
