How to auto-save owner email in custom form?

Hi everyone! I’m a beginner building a marketplace app in Glide (free plan).
I turned off the default “+” Add button because I want to create a custom form where:

  • The user can add a listing (title, price, category, image, etc.)
  • The listing should automatically save the signed-in user’s email to the “Owner Email” column
  • I want to make sure only the user who posted the listing can edit or delete it later

I tried creating a custom button to open a new screen for the form, but I’m confused about how to:

  • Add a form that writes to the correct table
  • Set “Owner Email = Signed-in user email” (since I don’t see the magic text or default value settings in the text entry)
  • Show the submit button and use actions like “Add Row” and “Set column values”

Can someone please guide me step by step, or send a sample app or screenshot that shows how to do this?

Thank you so much in advance :folded_hands:

You don’t need a custom form to do this, in a native form, you can add the signed-in user’s email to the “Owner Email” column.

In the native form, search for that column on the left panel and add it as a special value.
