Sum formula is not adding up properly
I am summing up hours in Excel and the sum formula is not working Properly.
For 2 of my 5 cells are adding correctly, but the other 2 when added to the formula throw the entire thing off. They are all formatted the same in 13:33 format to measure the # of hours spent on an activity. What would the reason be that two of them are not working? (it is almost like exel is substracting hours when these 2 cells are added) |

No real problem. Your math is probably fine; formatting needs fixing.
Select the cell with the sum in it. Format this cell as Time 37:30:55 -- Gary's Student "Michelle" wrote: I am summing up hours in Excel and the sum formula is not working Properly.

Gary,
I tried this. I thought this may have been the issue previously becauase at one point I had the entire sheet working, however when I added some tasks....it no longer worked. I have tasks compiled together, each one group with a sum and then the sum cells are totaled at the bottom. 2 of the sum cells are not summing properly. Any more ideas?

If there is a real calculational problem, one method of analyzing it is to
repeat the calculations in "natural" units. Say you have 5 times you are adding in cells A1 thru A5 with the sum in A6. In B1 put =A1 and format as number with 10 decimal places and copy down thru B6. This will allow you to see the times in "natural" units. Here is an example: 7:00 0.2916666667 8:00 0.3333333333 1:00 0.0416666667 10:00 0.4166666667 3:00 0.1250000000 ------------------------------- 29:00:00 1.2083333333 Looking at the B-column (which has the same numbers as A) will allow you to verify the math and insure that you do not have a 12 or 24 hour wrap-around problem. -- Gary's Student "Michelle" wrote: Gary, I tried this.

Probably stating the obvious, but have you tried a format of [hh]:mm?
