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

This function will render a return separated list of values that are in the newList but not found in the comparisonList. This is helpful, for example, to take a list of already selected items and still present them in a new picker list, allowing the user to make new selections.
