HI there,

I am so close but this will not add any values.
I do ctrl shift enter and it accepts the formula but I only get a 0.
Any ideas? Time cell is formatted as time and Friday is formatted as
General.

My approach to this is normally to restrict the range (initially) to
say three or four rows where you know you should get a result, then
examine the actual evaluations of the formula. For example, what
does:

(C100:C104="Friday")

evaluate to? Is it perhaps (FALSE, FALSE, FALSE, FALSE) when you
expected (FALSE, TRUE, FALSE, FALSE)?

If so, then you can focus on working out why, say, C101 <> "Friday"
when you think it should.

HTH,

Friday 8:00:00

where Friday is C2-C15 (or so) and 8:00:00 is D2-D15(or so)
my formula is not adding them up.
=SUM((C2:C7000="Friday")*(D2:D7000="8:00:00"))

is the data in column C actually the text string "Friday" or is it a date (ie
- a numeric value) that is custom formatted dddd to only display "Friday"?

Same for the time in column D. It is probably not a text string "8:00:00",
but rather a numeric date/time value. You might try

(D2:D7000=TIMEVALUE("8:00:00"))

Try the array formula:

=SUM((C2:C7000="Friday")*(F2:F7000=TIME(8,0,0)))

Or, this non-array version:

=SUMPRODUCT(--(C2:C7000="Friday"),--(F2:F7000=TIME(8,0,0)))

Thank you everyone, I will give these methods a try.

Hi,

If you do the test I suggested above (a couple or so rows will be
sufficient) what results do you get within the inner calcs?

Actually evaluate just the logical tests to get something like:

=SUM(({FALSE;TRUE;FALSE;FALSE})*({FALSE;TRUE;FALSE;FALSE}))

Pick any one that is wrong, then do something like:

=C101="Friday"

Presumably that evaluates to FALSE (based on the test being wrong).

Now evaluate C101 (or whatever cell you used) and see what it actually
contains.

HTH,

Hi,

thank you all for the help, the end result was ...
=SUM((B2:B16="Friday")*(C2:C716=TIMEVALUE("8:00:00"))) and it worked a
treat.
Keep on Geeking it up guys!

Glad you got it working.

These expressions do exactly the same thing:

TIMEVALUE("8:00:00")
TIME(8,0,0)

In your formula

=SUM((C2:C7000="Friday")*(F2:F7000="8:00:00 AM"))



"8:00:00 AM" is text, not time. Try


=SUM((C2:C7000="Friday")*(F2:F7000=TIMEVALUE("8:00:00 AM")))
