  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This CF allows to find out which values are new before adding them to the DB. It is useful to prevent duplicate entries when you do Insert from URL [] or when you need to post-process a set of newly selected checkboxes.

Works in FM16+ only (no runtimes).

Tip: To get the list of removed values, just change the parameters in places:

Quote ( @UniqueValuesToAdd ( "adding¶values" ; "existing¶values" ; "" ; "" ) ) = "existing¶"
