Recover Submitted Form

Can I recover a submitted form once I deleted.

It seems that your question is a bit vague. 

If you are asking about the deleted form, you can look in your "Trash" folder. If it was not purged, the form may still be there. 

But, if your question is about a form's submission, that is stored at your submissions page, then, unfortunately, it is permanently gone. We cannot easily restore them since we do not keep any other copy of them.

Hope this helps! But, we will gladly assist you if you need more help.
