Just a comment about UDF's not working across workbooks.

If your UDF is in a workbook named Book1.xls, you can refer to a function in
that workbook's project:

=book1.xls!ColorIndex(...)

If your UDF is in an addin, then you can refer to it just like it was built into
excel.

For those interested ..

Here's the revised sample, re-rendered incorporating Bob's suggestions <g:
http://www.savefile.com/files/378485
Count n Sum Cells By FillColor_BobPhillips_ColorIndex_UDF.xls

Note that UDFs need to be implemented in the very *same* book that the
function is intended to be used. UDFs cannot work across books.

Bob: Trust the revised sample is ok with you. Let me know.

Here's wishing a wonderful 2007 to all !!

Indeed it is beautifully rendered Max. If you intend to use this again,
may
I suggest that you also show how you can dynamically pick up the test
colour, that is by using

=SUMPRODUCT(--(ColorIndex($B$2:$B$11)=ColorIndex(E2)))
as I think this is a useful but not obvious feature (I know it could be
derived from what you do, but ...).

And also summing the values in the coloured range
=SUMPRODUCT(--(ColorIndex($B$2:$B$11)=ColorIndex(E2)),$B$2:$B$11 )

Hanyana,

Post back if Max's workbook doesn't solve the problem for you. I have
found
that most problems are caused by people thinking that the function is a
built-in, not one that you have to copy and input to the workbook. Of
course, that may not be your problem, but give us as much detail as you
can
if and when posting back.
