Hi,
First, you must have titles at the top of your columns.
Second, if the data and the titles are the same data type - (most commonly,
both text) Excel will assume by default that the titles are part of the data.
This does not happen if you have a title like Date and Excel legal dates
below it, or Amount with numbers below it. You can handle this problem by a.
putting a check in the My data has headers box at the top right of the Sort
dialog box, b. by setting the format of the titles differently from that of
the second line (data). You could underline the titles, italic, or bold
them, change the alignment to center, shade the cell or color the font among
others. c. you could define the range as a Table as suggested by Roger. (and
I have to stongly agree with him regarding using Tables, they will become the
method of choice for many thing, they were available in 2003 as Lists, but
nobody took note of them, I encourage you to practice with them as much as
possible, remember they don't need to have fancy colors, you can set the
style to None after you define the table.)
3. Third, the titles must include only one line to get good results and as
mentioned the line below the titles should be your data. An emply line or
something like ==== or ------ will mess things up.
