How can I find the edit link for previously submitted forms

I have several forms embedded on a Google site for users at different locations to enter in their monthly activity.  I now have several new employees and several people who are no longer employeed.The new employees need to be able to access the old employees submissions, however we do not have access to the old employees emails.

How do I find the edit link for each submission?  I have used the following and always get Invalid URL

http://submit.jotform.ca/form.php?formID={formID}&sid={submissionID}&mode=edit

I have tried jotform.com, jotform.eu, jotform.me, jotform.xml, myjotform.com, .eu.me.xml

I always get invalid url

Thank you for contacting us.

Please try the following format:

http://www.jotform.com/form.php?formID={formID}&sid={submissionID}&mode=edit 

Example:

http://www.jotform.com/form.php?formID=41956998135976&sid=281275555081927334&mode=edit

Where 4195699813597 is the form ID and 281275555081927334 is the submission ID.
