I have multiple "source" workbooks that are consolidated in a "target"
workbook. My concern is that the users may insert or delete rows, or
otherwise move data around, causing the target book to be in error. I have
been advised that the safest way to go is to link to named ranges rather than
cells.

Here is where I get confused:

In the Target workbook, Cell A1 shows the sum total of Cells B2:B5 in the
source book; Cell B1 shows the sum total of cells C2:C5, and so on. How do I
set the range names in the source book and how do I link to them?
