I have been reading for the better part of two hours trying all of your
suggestions. I am still unable to get the following data to sort. I have
formatted the cells. The data is similar to this:
1
2
5
8
10
13
3a
3b
4a
6a
7a
7b
9a
11a
12a
12b

With data going on up into the hundreds.
trying all the formulas that were out there did not bring me even close. I
am using 2007.

Thank you for your help...
