How do I edit the form that I made previously?

We want to reuse a previously made form, but can’t seem to publish it or save it with new details.  We’re building a new website, and would like to use this newly edited form on it, but can’t seem to change anything on the form.  How is this done?

Could you please share the URL of the form so we can check? If you wish to modify/edit the form, you can just click on the Edit Form button.

If you wish to duplicate the current form and make changes without changing the previous form, you can just clone the form and edit the cloned form.
