FileMaker Custom Function: Add To / Remove From Existing List

Simplify List Management With A Custom Function

Using lists in FileMaker is a common task and we do it a lot in the apps we design. Getting a list of records is relatively straight-forward, but it can get considerably more complicated when you want to manipulate that list by adding or removing values. In this tutorial, we'll use the code we developed for this purpose and turn it into a custom function you can reuse over and over again.
