I have a button for someone to sign up for a class. I want the button to just pass through their email address instead of getting to a screen to fill out a form and then hit submit without needing to enter anything else.
Is there an action that is just submit instead of opening the form?
Not that I aware of. Any changes make in your sheet and not recorded via the form will always be seen as a change from the sheet owner, so probably there’s no workaround without opening a form.
