Autoresponder email doesn't contain link to edit form

My autoresponder email doesn't include the text at the bottom of it:

You can {edit_submission} and {all_submissions} easily.

I have deleted the autoresponder several times & created a new one but none of the new ones contain this line which means the person who has filled out the form can't edit it.  The line appears at the bottom of the notification email but not the autoresponder. Please help!

Only the Email Notification has edit this submission and view all your submissions added at the bottom of the email template. 

If you want to allow your users to edit their form submissions, you will have to add an {edit_link} tag to the body of the Autoresponder Email. Inside of this guide, you can find hot to do it:

Hope this will help.
