hiding null rows from a matrix

All,
I have a matrix that is being populated by a sproc.
The sproc returns data which are broken into sections by fields and
then sorted by another field.
The matrix is group on the section designator.
However, each section is getting an initial row that is null.
I want to drop out the null rows from the matrix.
I am not allowed to change the sproc.
Thanks in advance,
MI have a couple of typos and things to add.
I was trying to say that the matrix is grouped on the section
designator.
within each section this is a null row showing up.
I just want the matrix to filter out the nulls.
I don't have that option to do it from within the sproc.|||Hi Max,
Did you find a solution for this, even I am facing the same problem, I need
to hide the empty rows in a matrix.
Please reply back if you have found any solution for this.
