Description:

Function removes the values an array has in common with a second array. I found I needed this function to check that two fields used as a multikey for a relationship (first field in equijoin, second field in a non-equijoin) are mutually exclusive.

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 Bob,
very good function, just searched for this functionality to subtract lists from each other to get an exclusive list.
I jut want to say, that I removed the "& ¶" after leftValues(Array;1) in the 5th line. This creates no empty lines in the result list

Cheers
Erik
