Karen,

Select your cells, then press Ctrl-H and replace the "pm" with " PM" ( a space and the two letters
pm) (and don't use the " marks). That will force Excel to re-evaluate all the values into time.

If I have cells that the time is entered as follows:
12:30pm (without the space between the time and the pm)
Can these times be used in calculations or does the time have to be entered
12:30 PM (with the space)?
Thanks, Karen
