hello,
I'm having a strange problem with a matrix headers.
I can't put column headers above each row group header. There is a
merged cell above them, which can't be split. If I have several row groups,
including Customer ID and Zipcode, I can't put headers above them to
identify them in the matrix. Since both have 5 numerals, they can be
confused.

Does any body know how to solve this?

Thanks in advance,
Roy.
