Forcing login for a frameset

I have a form where default access control is editor role, but I have button on the form which when clicked takes the visitor to a frameset.

I want to restrict access to this frameset, so how can I force the frameset to ask for login, now anybody who opens the form is also able to access the frameset.

any help is appreciated.

You seem to be saying that the default access for your web database is Editor.

It’s not necessary to give anonymous users this access just so they can fill in a form. Make it a public access form.
