Note: To install this custom function you must first install a second custom function called "CustomList".

Hello,

The function does not work well if the second list contains nothing. In this case the function returns the first result list.

Hello,

Yes, is my choice when I wrote this function : the calc are
" IsEmpty ( ListB ) ; ListA ;"

There was a discussion about it on the forum French, what is the logical result if ListB was empty... you can not put "IsEmpty (ListB), "";" because the result must depend on the selected attribute and I did not want to burden the already complicated calculation.
For Equal : IsEmpty ( ListB ) ; ""
For Not Equal : IsEmpty ( ListB ) ; ListA ;
For Contains or Not Contains.... What should be the result... The same for the other.

The easiest way was for me to decide if ListB was empty, the result was ListA.

But you may be right, I do not know.

Will this function accept global variables ($$myVariable) as ListA or ListB?
