Try this:
=SUMPRODUCT(--(A1:A1613="Saturday"),--(C1:C1613=TIME(8,15,0)),F1:F1613)
You can also replace TIME(8,15,0) with a reference cell
Hope it helps.

Yes, I tried it but it returned a #VALUE! error.
I used this:
=SUMPRODUCT(--(A1:A1613=--"Saturday"),(C1:C1613=--"08:15"),F1:F1613)
Is the error related to the format of "08:15", or the fact that
F1:F1613 the
cells containing the values are formula themselves? or have I made a
mistake
in the formula, it assumes that:
Days of the week are in column and timeslots in column C
If the SUMPRODUCT won't work, can I use the CONDITIONAL SUM WIZARD to
set
the 2 criteria, as I know it can do this, but I'm not quite clear how
to use
it. The SUMPRODUCT looks simpler and I would prefer to get that to
work!!!

D105, E105 contain numerical values and these represeent the data
used to
calculate the weighted average in F105 etc.
However, on reviiewing the problem and reading further on SUMIF
and
SUMPRODUCT, I don't think (???) I could use either of these as
there are 2
criteria to be considered in deciding which values are to be
added.
To restate the problem as clearly as I can:
I want to add all the values corresponding to particular timeslots
for
each
day over a given month and also to check if, for some reason, a
criteria
is
'wrong', e.g. the wrong timeslot it showing in the right cell (say
08:00
is
showing where 08:15 should show) that only values corresponding
with 08:15
will be summed.
I want to perform this calculation with all values from 08:15 to
21:00 for
all days of the week from Monday to Sunday for a month.
Example: (Jan 2005) relevant info in worksheet shows in:
A1: Saturday
C1: 08:15
F1 (Value to be summed, currently a formula, as in original post,
for
weighted average for all values at 8:15's on Mondays in January)
I've tried this, but it's not quite right, is it?
=IF(C105=0.04375,SUM(H105:H1613)
(I've converted "08:15" from time format to a number and have
retyped the
value in f105 as a number into h105) and this gives me an answer
for all
8:15's in the range f105 to f1613
The problem arises when I try to include an additnal IF statement
for the
2nd criteria 'Monday'
If I ADD in after the above:
=(IF(A105="Monday",SUM(h105:h1613), it returns a 'TRUE'
This reads (in full)
=IF(C105=0.04375,SUM(H105:H1613)=(IF(A105="Monday" ,SUM(h105:h1613)
So, 2 questions:
How do I combine the 2 IF statements to get a result? (i.e. the sum
of the
values)?
Is there a function or Visual Basic code I could use to convert
the
weighted
average formula in f1:f1613 without the need to retype them all?

I would like to use this function to sum particular values but
I
realise
that
the function will only work with numerical values.
The values I wish to sum are weighted averages based on figures
which
are
not in a range, and the formula shows the distribution of the
data:
=($D105*$E105)+($D469*$E469)+($D833*$E833)+($D1197 *$E1197)+($D1561*$E1561)/(
$D105+$D469+$D833+$D1197+$D1561)
I know that if I simply retype the values as numbers the SUMIF
will
work
fine, but there is a vast amount of data involved and it will
be very
time
consuming and tedious I'm hoping there is a way of converting
the
formula
to
a numerical equivalent in the adjacent row. I have tried =(g1)
etc but
this
doesn't work with SUMIF either.
Can it be done?
