I have used the sumproduct function a lot and thinks it is very good. My
problem is that I do not know the functions of different characters that can
be used in the sumproduct function

Ie. what is the "--" in front of a sumproduct function : "Sumproduct(--(xx
and when to use "*" and "+" and ",".

Does anyone have any "guide" to sumproduct that can explain theese things
and probably other things?
