Although I've been developing with Filemaker for many years, I came across a variant of the Set Field script step in a database I recently inherited as a maintainer. Actually two of them>
Set Field [Customers::g.CustomerID; Customers via GroupID::Serial Number] and
If [Count (Customers via GroupID::Serial Number)=1]
I've never seen via used before. I was wondering the significance of it and what the suggested uses are.
