group header visibility problem

I have table with two group headers.
I want my data to look something like this:
-Group1_master data - header1
-Group1_master data - some description - header2
-Details of group1.....
Now, i want to display this header2 only if descrpition contains data, that
is not null, and i wrote expression like this:
=Iif(Fields!Description.Value = Nothing, "True", "False")
.. and put it in the Hidden property of table row that is actualy ma header2
But that header2 is never hidden, i realy dont know is that a known problem
or im missing something.
tnx for any replaysTry changing "True" to true and "False" to false:
=iif(Fields!Description.Value = Nothing, true, false)
