What happens if I edit my form?

My responders are not able to receive auto-respond on their emails. Is this because I have edit the form after I sent out the original link to them?

I was looking at the link of the form and even after several edits, it is still the same.

Link of the form will always be the same, even if you edit your form. Your issue with Autoresponder emails is not related to editing of your form. 

I saw that you have opened another thread regarding your issue with Autoresponder emails. Please see an answer my colleague provided you on that thread:
