Multiplication problem- Please Help!

Hello all. I am a novice Excel user, and cannot seem to locate the source of my problem. Please help!


Here is my sheet:


C4 D4 E4 F4 G4 H4

9/22/2005 7:10 PM___10/1/2005 12:13 PM___ 8.7__52.6__6.0__317.64

Start date is entered into C4.
End date is entered into D4.

The following formula is in E4 to determine elapsed days:

=IF(D4=0,"",IF(C4=0,"",(IF(ISERROR((D4-C4)*24),"",(D4-C4)*24)/24)))

F4 contains "FLAGED HOURS" (for a body shop estimate)

G4 contains a value used for "cycle time" and is using the following formula:

=IF(F4=0,"",F4/E4)

H4 contains a simple multiplication formula: =(F4*G4), but returns 317.64 INSTEAD of 315.6 (which is 52.6 x 6.0). I need the 315.6 result in H4.

Would someone please tell me what I am doing wrong????

Thanks very much!

This appears to be a rounding problem....Try changing the foemula in H:4 to =F4*ROUND(G4,0)

The cells contain trailing digits which you are not seeing.

You could try

=(ROUND(F4,2)*(ROUND(G4,1)))

Well, I need more help on these sheets. I've made two attachments (I wish I could figure out how to imbed an image directly into the message here...)

On sheet 1, this is the code to figure the required date for a cycle time. This is from column F-

=IF(C3=0,"",C3+(D3/E3))


This is the code from column G, that tells me how many days between C and F-

=IF(F3=0,"",IF(C3=0,"",(IF(ISERROR((F3-C3)*24),"",(F3-C3)*24)/24)))

I need the formula to exclude Saturdays and Sundays. Is this possible? If possible, it would be great to have it display " x days x hours" instead of "5.8" days.

On sheet 3, I am using the same code-

=IF(D3=0,"",IF(C3=0,"",(IF(ISERROR((D3-C3)*24),"",(D3-C3)*24)/24)))

...to tell me how many elapsed days between C and D, and still need the same fix, as above.

Please help!

Try using Excel formula: =networkdays(start date,end date). You can even
exclude holidays using this formula. First, though, you have to go to Tools,
Add-Ins... and select the Analysis ToolPak. Takes about two seconds to do.
The Analysis ToolPak give you a choice of lots more formulas.

I've tried incorporating the NETWORKDAYS function into the current formulas, but can't get it to work. Playing with NETWORKDAYS on a blank sheet, it rounds to the day. I need results to the hour. Any further help, or examples using my formulas?

Thanks!

Can I confirm what you want to do?

Do you want to calculate the number of days and hours between two date/times (excluding weekends) or do you want to generate a date/time based on a number of days (possibly fractional) added to a start date/time? (or both )

If the latter then how many hours constitute a day? If you add 1.2 days to 18:00 on a Monday what should the result be? Do you want the time returned to be any time of the day or should it be within specific hours, e.g. your working hours, if so what are these?
