Subtraction when including the MOD() function
Hi, I am trying to do some simple math, but it will include the MOD function, and I can't get the result I need. what I have is one column of datetime (dd/mm/yy hh:mm) and another column of just time (hh:mm). I need to subtract the TIME ONLY in the datetime column from the time column. This is what I thought was right, but it doesn't seem to be. =(K3-(MOD(MARIE_STATS!A3,1))) The answer I get is -0.82 if the cell is formatted as a "Number". If I try to format it as "Time" (hh:mm) I get all #########. The actualy value in this case should be 00:37 (37 minutes. So, somewhere I be messing up, can someone straighten me out please? FYI cell K3 is the higher value so I shouldn't bet a negative.

Brian,
Your formula works fine for me, where A3 is date and time, K3 is just time. Is that what you have? -- HTH Bob Phillips (replace somewhere in email address with gmail if mailing direct) "Gadgets" wrote in message ...

FYI cell K3 is the higher value so I shouldn't bet a negative. What are K3 and A3 exactly? If your formula does return a negative number, then Excel won't display it in Time formats unless you use the 1904 date system. [Why Excel can't display negative times in the 1900 date system is one of the universe's deeper mysteries.] Note that the absolute value of the result, 0.82, is more than 19 hours rather than just 37 minutes, so it looks like there's something wrong in either K3 or A3 or both. |

Yup, here are my exact values in the cells in this example: K3= 20:15 A3= 05/04/2005 19:38 I want to subtract the 19:38 portion of A3 from the 20:15 in K3 (just want to make sure we're on the same page here. :-) ) Thanks for the assistance Bob!

Subtraction when including the MOD() function
D-O-H-!- Got it working, stupid me forgot to add what sheet I was pulling the information in K3 from. adding that, gives me exactly what it should have... I can be so stupid sometimes! However, I am new at this excel stuff.. that should count for some level of stupidity!
