changing automations trigger

Hello, I picked the automation to trigger when any form is submitted. I changed my mind and want it to be triggered only when a specific form is submitted. When I click new automation it no longer gives me a choice and only gives me the option of form submitted. How do I change my options? Thanks in Advance. Rick

Wix Automations have their own Wix Support pages that you can read through.

You should just be able to go back to the original automation and rechoose the trigger that you prefer.
