SUMIF where values to be summed are formula

Z

Zakynthos

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?

What are in the cells D105, E105 for example, results wise?

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?

Did you try the SUMPRODUCT solution offered earlier? If so, what was the
problem?

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!!!

Should be

=SUMPRODUCT(--(A1:A1613=--"Saturday"),--(C1:C1613=--"08:15"),F1:F1613)

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.

Thanks, I see I missed a couple of -- but on adding it in, I'm still getting
#VALUE.

The conditional sum wizard should do the job, I think I've now figured out
how to use it properly.

I've read that SUMPRODUCT is the most powerful and flexible Excel function,
but I've got nowhere with it.

Anyway, many thanks for all your help and advice.

Regards

Tony

Sorry I missed that you added some extra --, should be

=SUMPRODUCT(--(A1:A1613="Saturday"),--(C1:C1613=--"08:15"),F1:F1613)

but if column A is dates it should further be

=SUMPRODUCT(--(TEXT(A1:A1613,"dddd")="Saturday"),--(C1:C1613=--"08:15"),F1:F
1613)

or

=SUMPRODUCT(--(WEEKDAY(A1:A1613)=6),--(C1:C1613=--"08:15"),F1:F1613)

Many thanks, I've tried it and it works just fine, BUT ........

It ONLY works without returning a #DIV! OR #vALUE! etc(or, rather, I can
only get it to work) if I manually retype the values in F1:F1613 into
adjacent cells and change the F1:F1613 ref to the column into which I've
copied the values, eg G1:g1613

There are a vast amount of values to convert from, so I could only really
use the formula if I can get these formula converted to values instead of
retyping them all.

Is there a Visual Basic program I could write or an Excel function that
would allow me to do this?

Bob,

Thanks, I'll give it a go!
