Retains only unique values from list

Sample Input:
UniqueValues( "a¶b¶b¶c" )
Sample Output:

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


Takes a return-seperated list as parameter and outputs a list of the unique values from this list. This function can be used in conjunction with the FileMaker List() function to mimick the good old value list items behavior, without creating a ValueList.

This is my Custom Function and I want to edit it

Could you use a global variable $$list_of_values as the argument values?

Dave, yes you can! Just pass your global variable as a parameter to the function, as in:

Set Field ["NewList" ; "UniqueValues ( $$list_of_values) "]

GREAT function. Thanks! I was looking for an alternative to producing this kind of output without using a portal.

Quick question: Is there a way to filter a value using this CF? For example, say your (finished) list is:


...and you want to omit 'bravo' from the list, is there a calc I can wrap around this CF to do that?

Beware of using this function if you are running FileMaker 16 or greater, on server or client. FM 16 introduced an identically named function, and this causes conflict.

Please rename this CF!

Daniel, You are absolutely right. This function has become obsolete since FileMaker implemented it - finally :-) - itself.
