Published links to specific Dynamic Forms, like the HR's Flexible Spending form, will almost always start a brand new form.  If you started a form but did not finish it (and it let you save progress), you will want to login to Lesley's Dynamic Forms site and go to your Pending/Draft Forms.  Do not go back to the link for the specified form.  If you are a form designer, use the My Forms link on your admin page.
