Thank you for your response. I went back in and i was able to figure out what i was doing wrong.
I did not bind the value to the name i assigned the file name. It then appeared in the attachment section of the email portion of the UI.
Another issue that i am finding is that when i try to create multiple file uploads in the form field is that they are not available for me to select under email attachments and when i try to select finish DW will crash periodically.
