Excel service problem |in browser view of worksheet(excel sheet)

I created a new worksheet in Excel 2007and created number of named views to show different part of excel sheet .

But when i published it to my sharepoint site and open it in Browser view then I m not able to see all those views in a dropdownlist at the top of worksheet.Same thing is available and visible in sampleworksheet available in sharepoint 2007. Can anyone suggest me a right way of doing same and if there is any configuration that is to be made.
