Return value based on fraction of a list

[philiph]

In $U$8:Ux I have a variable length list of sizes. In $Q$4 I have a
number (1, 2, 4, 8, etc), that is used to divide $U$8:Ux into more-or-
less equal sections/fractions. In $P$8x I need to return a set of
values (1 - Q4) that reflects the fractions in $U$8:Ux (ie they would
be the numerator of the fractions). Eg:

P U
1 23
1 16
1 1.5
1 85.6
1 23.4
1 12.8
2 45
2 23.6
2 56
2 105.1

So far this formula is getting there, but I can't work out how to
finish it such that it accommodates ANY value in Q4.

=IF(SUM($U$8:U8)<SUM($U$8:$U$75)/$Q$4,1,IF(SUM($U8:U$26)<SUM($U$26:$U
$75)/$Q$4-1,2,IF(SUM($U8:U$26)<SUM($U$26:$U$75)/$Q$4-2,3,"Other values
that I can't work out")))


Can anyone help? Preferably a formula but VBA would be good too. Don't
worry about the SUM($U$26:$U$75) bit: I can make that take the column
length into account.
thanks,
Philip

's OK: Rik over on .worksheet.programming has given me the solution.
