I am trying to subtract 12 hours from a date/time cell if the date in B1 is
greater than A1.

A1 3/3/2010 2030 (formatted: m/d/yyyy hh:mm)
B1 3/4/2010 1030 (formatted: m/d/yyyy hh:mm)

No matter how I format A1, B1 and C1 I still get a #Value error. I am
obviously missing something or leaving something out. Any help is greatly
appreciated.
