Excel sheets are not moving

can you copy the error message? I am not able to see what error you are getting!

Excel cannot insert the sheets into the destination workbook, because it contains fewer rows and columns than the source workbook  to move or copy the data to the destination workbook, you can select the data and then use the copy and paste commands to insert it into the sheets of another workbook.

It seems that You are copying a sheet from excel 2007 or higher to a workbook of excel 2003.

Sorry.. Not sure why this error comes. I first create a new workbook (Ctrl+N); then I just rightclick on the pane and select move or copy. In the pop-up window, I check "Copy" and in the dropdown I select the new workbook (Book1).
