I agree.

$CASE(1,
%source.userActionone:"User action one", 
%source.userActiontwo:"User action two",
%source.userActionthree:"User action three",
%source.userActionfour:"User action four", 
%source.userActionfive:"User action five", 
%source.userActionsix:"User action six", 
%source.userActionseven:"User action seven", 
%source.userActioneigth:"User action eigth", 
%source.userActionnine:"User action nine", 
%source.userActionten:"User action ten", 
%source.userActioneleven:"User action eleven", 
%source.userActiontwelve:"User action twelve", 
%source.userActionthirteen:"User action thirteen",
%source.userActionfourteen:"User action fourteen", :"Other")

But the result will still be only one value, even if all %source.userActionXXX=1.

What result should $select return if the conditions
%source.userActionone=1 AND %source.userActiontwo=1 are true ?
