Hi all

I am trying to subtract 24 hours from a time if it is actually over 24 hours, if not then show 0

my formula works for everthing over 24 hours but can't get it show a 0 or under 24 hours.

In A1 8/3/2008 7:21

in B1 8/6/2088 15:36

in C1 I have =if(("B1-A1")(A1+"1"),(B1-A1)-"1",0)

The answer is 56:15:00 which is what I want but if B1 is 8/3/2008 it is showing ##### indicating a negative time number

instead of 0

any help would be appreciated

Richard
