On the Project record, I want to have a field called "Project Budget"; I want this (currency) data to come from a field on a custom record (Project Budget Input), which at this point only has (needs?) two fields: Project (list/record from the Project record) and Budget (the field I want to pass through to the Project Budget field on the budget record).
My setup on this is not working. I would assume the field on the project record needs to be currency, matching the budget input field on the custom record. However but the Project Budget Input record is not available as a Source List.
