I am using MS Office Excel 2003 (11.8307.8221) SP3 on MS Windows XP
5.1 (build 2600.xpsp_sp3_gdr.090206-1234: SP 3).

I have the following list of numbers.
C-B
0.044991
0.012016
0.027636
0.187865
0.01452
-0.104374

I try to sort them by highlighting them and choosing Data:Sort
Sort by C-B. Header row, TRUE.
The numbers remain unchanged.

What gives?

Many thanks in advance,
Peter.
