I'm trying to create a 'download your free copy...' form for a PDF, with a 'Download' button that both stores the data in a Google spreadsheet (done) and downloads the document.
I can add a simple download link in the post-submit HTML, but this is an extra click for the user and potentially confusing after they've already clicked 'Download'.
So, I'd like the PDF to be automatically downloaded when the form is submitted.
I've tried adding some Javascript, e.g. as per this thread, but nothing has worked.
Is there some way to achieve this?
Thanks!
