Currently we don't support pre-filled field values. If you want to provide instructions to your form recipients, you might consider using a Formatted Text item. The recipients will be able to copy the text from the body of the HTML form.
Thanks for the response Brian... I fear that wouldn't work. It's not important that the form come back to me with the text...only that it go out with the text and come back with the mp3 attachment.
Any chance this will be coming?
OK. So something like the introduction text at the start of the following example form wouldn't work?
Are you concerned about the content not being formatted correctly in the body of the form?

Note that if you were to deliver the text in a pre-filled field you would receive the script in each submission in the response table, in addition to the attachment. If you could provide the text as a Formatted Text item, the text wouldn't be included in each submission.
