Excel 2007 names have scope: workbook or worksheet. Thus you can use the
same name over and over to name a cell or range on different worksheets and
once at the workbook level. You can use the name on the sheet where it is
defined without qualification. You can also use the name to refer to other
sheets that have the same name if you qualify it with the appropriate sheet
name. If the same name is defined at the workbook level and you use it on a
sheet that has the same name defined, you can qualify it with the book name.
If you use the name on a sheet that does not have the same name defined, you
get the workbook level name unless you qualify it a sheet name to get the
name as defined on that sheet.
