[Docassemble] Errors with producing documents

Hi, I'm having two issues simultaneous issues that are stumping me - First, a user gets to the page for downloading documents, but when he clicks on PDF or DOCX, a browser tab opens up and nothing downloads. When he tries to send the attachment by email, he sees the error: "invalid name _attachment_email_address" In the other, my attachments successfully email, but the last page that should also display a couple of the attachments won't render. Instead I get an error: TypeError: can't pickle instancemethod objects Any idea what might be going on? Thanks!
