excel 2007 sort problem

[cindy]

I have an excel 2007 worksheet - originally in 2003. All I need is a sort by
last name/first name - which worked fine in 2003 using A-Z - but now I can
add new names and they do not sort correctly??? It's a basic alpha sort,
works randomly..
Anyone have any idea what the cause might be, or what to look for to trouble
shoot it????

any advice would be appreciated!
thanks - Cindy

Excel 2007 sort works basically the same as Excel 2003, except you can sort
up to 64 levels.
Do you have your last names in one column and first names in another column
or are the names in one column like Lastname, Firstname?
Give us an example
