I thought I had cracked it but still having problems with this. Can anybody
help???

Basically it`s to do with flying hours budget between Medical and Police.
Medical contributes 30% of the running costs and the Police the
rest up to 40 hours per month and 25% over a combined 40 hours.
What I'm trying to do is to know the break down of hours between both units
and what percentage each use for the first 40 hours and then over that.
The trouble is that not all the hours used by Medical fall under 40 hours,
some will fall over that figure. You might have a situation when there is no
Medical flights under 40 hours and all of it over. So they should only pay
25% of the running costs.
The cells used are as follows:
Cells:
H3 = The reference figure (40 hours)
H9 = Total Med under 40 hours
H11 = Total Med over 40 hours
J9 = Medical percentage over 40 hours
J11 = Percentage under 40
H7 = Total Med hours
(note C18 is the grand total of both units)

Polioce are the same but cells start with "N" for the hours and "P" for the
percentages

I hope that gives you more of an idea on how the lay is.
Data is entered on a table A11:D60000.
