Let's imagine it was another sheet that you wanted to look in (in the
same workbook), and the sheet's name was held in a cell - you would
use INDIRECT to do this.

However, INDIRECT will not work with closed files, so if you wanted to
have a filename and sheetname in a cell then you would have to arrange
that the second file was open at the same time.

Hope this helps.
