Matrix won't collapse

I have a Matrix displaying my OLAP based dataset. The dataset looks correct
and the MAtrix displays properly with all rows and columns expanded.
I don't have the ability to collapse or expand any of the rows or columns.
No + - icon displays either.
I have tried changing settings for the initial display of columns as
collapsed and expanded.
Any ideas on the problem?
JimOK... I got it.
The visibility needs to be set on the groups.
