Good chance that Excel sees the "numbers" as text, especially if copied from
somewhere else.

Select the numbers and DataText to ColumnsFinish

Try the sort again.

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.

Thank you for your reply. Unfortunately that did not work. I should
have mentioned that the data was in column I. I obtained the first
element with =$C2-$B2 and dragged the cursor down to get the remaining
elements in the column from the values in columns B and C.
