PDF forms don't work well online unless you KNOW all of your viewers have their systems set a specific way. Depending on a viewer's settings, PDFs can either display in the browser, display in Acrobat or simply download to their machine. There is no way to control what happens when you link to a PDF in your web page unless you can control all of the viewer's machines that will see it (company intranet for instance). You will be much, much better off re-creating the PDF using HTML Form Elements within DW on a standard .html page. Then, depending on what your server supports, attaching that form.html page to a server-side form processing script. If your server supports PHP, I suggest a premade script like Formmail from http://www.tectite.com. It is a very robust script with many optional features for things like security, file upload, etc. Their website also gives you a ton of info on how to implement it.
