Hi Peter,
In 2005 I'm able to do this as mentioned earlier, but the problem is with 2008 .
I have followed the steps you have mentioned.
The sorting tab also was showing the same expression = Ceiling(Rownumber(Nothing)/10) ,then I have removed it.
And completed the steps given by you.
But I'm getting an error as below:
"
The Value expression for the tablix ‘Tablix7’ contains an error: [BC30654] 'Return' statement in a Function, Get, or Operator must return a value.
"
Thanks & Regards,
MC
