For each item in list 1, counts occurrences in list 2

Sample Input:
Distribution( "A¶B¶C"; "A¶A¶A¶B¶A¶B")
Sample Output:
A (4)
B (2)
C (0)


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

Description:

For each item in list 1 (uniquelist) , counts occurrences in list 2 (datalist). So for instance list 1 could include list 1 could include Seattle and Portland, and list two could be the result of a list function that accumulates the "City" field across a record set.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Hi, Bruce. Handy function I used right away. Found a small fix that corrects where the value should be bold if matches > 0 rather than > 1:

Let([
v1 = GetValue( uniqueList; 1) ;
listLength = ValueCount( uniqueList ) ;
matches = ValueCount( FilterValues( dataList; v1));
listremainder = MiddleValues( uniqueList ; 2; listLength -1) ];

Case( matches > 0; TextStyleAdd ( v1; Bold ); v1 ) & " (" & matches & ")" &
Case( listLength > 1; "¶" & Distribution ( listRemainder; dataList )
)
)

The original cf works correctly for my intentions; it only highlights the items with more than one match.
