If you're referring to the detail area below the form, for the Program template, that will show the web page content for the URL attribute, which is not normally editable. You can enable web page editing, but only if the document is stored in UR (see

Another possibility is that you want to base your template on the Text template, which displays a rich text editor, rather than browser content, in the detail area.
