I am needing the forms to be linked with something other than an email.

I am needing the forms to be linked with something other than an email. As multiple forms will be filled out by the same person (i.e same email address)

I created an additional field called Unit ID. So they could enter a unique ID for each session. But this doesn't seem to be working. I tested it with three random ID's 555, 3430, 2222

and I then partially filled out one form and closed it down, now no matter what email I return to the info is the same prefilled data. Is there a way to create separate sessions so this form can be filled out separately based on the Unit ID?

Thanks

As long as the assigned session value are unique then each customer's saved data are segregated.

Example: Assuming that the field tag of the Unique ID is {unitID}, then the session URL parameter should look like this:

?session={unitID}

You should make sure the hyperlinked has the same field tag {unitID} too.

If you can provide to us the form you're working, we'd be glad to inspect it here.
