permissions - sharepoint public form -

I have a site that is a public face on which an anonymous user can fill and save, but I think that Only empty forms are visible to an anonymous user and the form filling by other users is not visible to unknown users.

For this, I have a form library (Form 1), which is certification-protected, and other form libraries (Form 2) which is available to the public. My system is that anonymous users fill forms from Form 2 , And saves it in Form 1. But when applying it this way, I get the "Error submitting form" error.

Any thoughts?

You can create simple workflows that can move a new document protected from the public document library. Or you can email document library to fill in the secure document library as an attachment.
