converting an rdlc report from 2005 to 2010

Hi,

I have a rdlc built in VS 2005.Now i intend to move it to 2010.
So i opened the solution in 2010 and i have imported Microsoft.ReportViewer. version 10.0.0.0 dlls to my project.

All the tables are rendering data properly.

But one of the tables either does not display anything,it displays Empty cells

or it displays "#Error" .

Is it a prob in the textbox Expression ?

or Do we need to set any other things while migrating to 2010.

Please help.
