Hi - Using the formula wizard I tried this statement:

SUBSET_UNIQUESLIST([Field 2], SUBSET([Field 2],NULL,'<>'))

and it works fine, returning the list of non-empty in [Field2].

However, when I tried it in a script defining an array:

var array = subset_uniquesList('ABICapoGruppo', SUBSET('ABICapoGruppo',NULL,'<>'));

it returns the message that NULL is not defined. Which is the way to express the NULL values in scripts?

Thanks
