HTML?

[West]

I am wondering if its possible to add a HTML code?. here is what I am trying to do. I am set up with Commission Junction and I am a affiliate of a company. so I am able to sell there products in my catalog, but to be able to add their products I have to add this HTML, here is what it says "Copy and paste the following HTML code into your web pages." so I paste the code in the Products Description along with filling out the price, date and so on. then I hit preview and everything seems to look ok all but the price stayed at $0.00 so when I tried to hit insert it does nothing, like the link is dead and also the back button is the same way, the cancel button seems to work fine but not the other two. Is it possible to add a HTML code like the way I am doing? or is there a mod that will allow me to do this?, Thanks for any help
