Hi,

I've got a large worksheet doing a variety of calculations. One section of
the data looks like:
A .... F G H
6 one four
0 one
25 three three
9 two two
4 one
0

Column A always contains a whole number or 0.
Column F contains one of a set of text values defined in column G. If Column
A is zero, Column F will be blank.
Column G is a list of possible values of Column F, sorted in alphabetical
order.
I have no way of knowing what values are in Column A, nor how many rows are
used (though I can set a high limit and unused rows will contain zero).
I have no way of knowing what value is in column F other than the limits
described above.

What I need to do is SUM the values in Column A according to the value in
Column F, so columns G and H would look like:
G H
four 0
one 10
three 25
two 9

Help on the formula to do this would be much appreciated.

This is in XL 2003 if it makes any difference.

TIA

Dave
