i'm trying to add the buy now or add to cart tag to a app, but can't get it to work for me. Have been reading the other disucussions but can't make any sense from them. I'm only new to bc and would really appreciate some step by step screenshots of how to achieve this. Thanks in advance

Hey Guys thanks for all your help, have one last request from the client they would like to see a list of products on the page down the side.

The products are all in a custom web app with custom fields all set up, the problem is i've already used the list template, alt template and the detail template in the layout. Is there any other way to get a list of web app onto a page?

Just noticed another problem i'm having, under the pages i'm seeing four of the layout files from my Web Apps that were created. They weren't there the other day and can't workout how to make them go away again, don't really want the client to see the layout pages or to accidentally delete them.
