What browser (and its version) are you using to fill out the form?
Hi Genevieve ... thank you much for the quick response ... I was trying to open the form through safari browser 5.1.8 then email content through mac mail 4.6 so I could have participants fill out directly in the email message but I have switched gears and decided your PDF forms feature will do the same thing and it maybe even better to fill out at leisure on desktop than what I was thinking ... thanks again
Were you trying to embed the form in the email message itself? This is not supported. You need to email the link of the HTML form. Glad to hear that the PDF format works for you.
