I've tried about everything I can think of for this, and come up blank....so resorting to asking instead!
I have a number of custom fields in my database I use for things like different spellings of artists names, and I want to create a Pane View that lists all of those tracks where the artist is not the same as my custom field.
In this case my custom field is called "Artist List".
So I'm trying all of this in the pane customisation dialog, Include Files ... Set rules for file display, as that sets the rules for the pane.
You can't seem to use standard rules as they only seem to compare the database library fields actual values, not other fields values, so I am trying to write a custom rule.
I've tried -[Artist]=[Artist List] which returns everything, does no filtering at all, it seems to treat [Artist List] as a literal.
I tried -isEqual([Artist],[Artist List]) which returned nothing at all, and broke the rule out into two separate custom rules.
I tried -compare([Artist],[Artist List],0) which returned everything again, no filtering at all.
I've tried with and without the - sign to not the expression around and that appears not to do anything at all.
I've also tried this in the search dialogue as they appear to follow the same rules, but can't get that to work either.
Any Gurus any ideas? Thanks
