Sorry Richard, I list your email address.

Here's my comment:

page 5 page 6


amount $ amount $
1400 452
5000 77
2400 64
752 11437 <-- from A13: =A13
1885 90



sum of G5:G9 sum of I5:I9
11437 <-- =SUM(G5:G9) 12120 <-- =SUM(I5:I9)

Any change in the "page 5" column G5:G9 will change the sum in A13 wich
will then change the value in the page 6 column I5:I9 which will
change the sum of that tange in D5.

If in this context you get wrong results it may have to do with the
autosum feature.

Let me know if it works.
