Is the embed option on the distribute tab not available in the trial version? If it is not, is there another way to test this function with the trial?
The "Embed" option is not a paid feature, it is available in the "Free" level account.
Is your form an "Imported PDF"? There is no option to embed for an imported PDF, they are distributed as PDF only and not available "online".
If your form is a form created in FormsCentral and you don't see "Embed" on the Distribute tab you can share your form with me at firstname.lastname@example.org following these instructions and I can take a look (please reference this Forum thread in your invitation): http://forums.adobe.com/docs/DOC-2462
The form was imported. Thank you.
