I am trying to get a min and a max value in column C for the various
Registrations in column B in a spreadsheet - Excel 2003. ie trying to get the
first and last kilometer reading of the month per vehicle. Please can you help

A-DATE B-TRUCK REG C-KILOMETERS D-DIESEL FILLED
1 1/5/08 JWY467GP 10000 1000

2 5/5/08 PTS030GP 5000 500

Use F1, say, to enter the month you are interested in (as a number 1
to 12), and list your registration numbers in column F starting with
F2. Then in G2 you can put this array* formula to get the maximum:

=MAX(IF((MONTH(A\$1:A\$100)=F\$1)*(B\$1:B\$100=F2),C\$1:C\$100))

and this one in H2 to get the minimum:

=MIN(IF((MONTH(A\$1:A\$100)=F\$1)*(B\$1:B\$100=F2),C\$1:C\$100,10E10))

I have assumed that you have up to 100 rows of data - adjust if you
have more.

*Array formulae need to be committed using the key combination of CTRL-
SHIFT-ENTER (CSE) rather than the usual ENTER. If you do this
correctly then Excel will wrap curly braces { } around the formula
when viewed in the formula bar - you should not type these yourself.
If you amend the formula you must use CSE again.

However, you can use the normal copy/paste operation to copy G2:H2
down to cover the number of vehicles you have.

Change the number in F1 to choose a different month.

Hope this helps.

Hi Pete

Thank you for your help, the adding F1 Month will certainly help.

Good Day

I am currently using the below formula for min and max value by month(). I
would like to go a step further now and recover the min and max value between
2 date values. ie. diesel used between January to April

Appreciate the help
