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

Thank you for the function. However, I notice that if I have multiple (or any) null values e.g. "a¶¶b¶¶b¶c" the return is "a¶¶b¶¶¶c¶" rather than the expected "a¶b¶c¶".

The following change will deal nicely with this case:

l = values;
v= GetValue(l; 1);
newL = RightValues( l ; ValueCount( l ) - 1)
] ;
l = "" ;"" ;
v = ""; UniqueValues( newL ); // Eliminate null values here
If( ValueCount(FilterValues(l; v)) > 1 ; "" ; v & "¶" ) & UniqueValues( newL )

Good point, thanks! I changed the function definition accordingly.

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?
