Hi,
I was wondering what -- does. I'm assuming -- does not mean +. Specifically, I saw one example from Contextures with:
=SUMPRODUCT(--(ColourList=B15),(UnitsList),--(DateList>=$C$2),--(DateList<=$E$2))
Although I'm specifically referring to sumproduct, if it has different meanings/usage elsewhere, I'd be interested in knowing about that too. If you know of a website that explains it, that would work fine too. (-- isn't an easy thing to search for)
Thanks,
Scott
