(!idspnExcel_NV) cannot determine which row in your list or selection contains column labels, which are required for this command.

• If you want the first row of the selection or list used as labels and not as data, click OK. 
• If you selected a subset of cells in error, select a single cell, and try the command again.
• To create column labels, click Cancel, and enter a text label at the top of each column of data.
