Allowing edit of a record without login?

Allowing edit of a record without login?

Is there a way to allow someone to edit a record without logging into ZOHO Creator? 
 
I have a form that emails users in a list when a record is added.  Once they get the email, there is a link where they can respond Yes or No.  If they choose Yes, then a hidden field is supposed to change to Yes as well.  If they choose No, then nothing happens and the record remains unchanged.
 
If I am logged in, this works fine and there are no issues.  If I am not logged in, it takes me to the form from the email link, and when I choose Yes, it submits and looks like it works, but it does not edit the record.  Is ther a way to allow the record to be edited without a login? 
 
I have already changed the permissions to all the views in my project to Allow Add and Allow Edit.  The application is also set as public...
 
Any ideas?
 
Thanks!
