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

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?
