edit submit button

I'm not sure what you mean by you have your submit button as a link. The submit button is a button, not a text link. If it isn't appearing on your form it is most likely because you have configured conditional logic to hide it.

Check to make sure you haven't added conditional logic to hide your submit button. This is found under Form Settings under the Advanced Tab. There is a checkbox "Enable conditional logic" see this screenshot: http://grab.by/aaRc

Other than that it isn't clear what you are talking about. If you can provide a link to the page containing your form we can take a look.

The Edit Form link that you see appears below the form if you are logged in as an admin, users don't see that link.
