Hi Matlow99,
What is your goal here? Is it simply to add two fields to the screen?
(1) You mention the screen creates a new contact but doesn't update the original, are you wanting to update or create a new contact?
(2) Method will not sync your custom fields with QB, but everything else should. However, only the primary contact will sync with QB. If you are adding another contact they will not sync over.
(3) Have you added the merge fields correctly?
It seems like the fields are not being updated correctly. Have you added the additional "Update fields into table" actions for your new fields?
