thank you for fast response!
but its still not clear to me, sorry
After form submission I want to open the generated PDF file
we added the shortcode for inline. So we click the download PDF button from a formidable form then it is going to a page which then we have to click a link to get the PDF to open rather than having the PDF pop open in a new browser window immediately. Maybe I am missing something?
Any help would be appreciated.

ALso when we submit the form we want it to attach and send the PDF via email but it is not working either. Is it possible for you to login to see what we are doing which may have caused this issue??

Thank you for helping.
