seaching for info between dates in a table

Basically I have two groups of data



Group 1 is machine info and has



Serial Number Build Month Commission Month





Group 2 is warranty info and has



Serial Number Service Claim Value of Service Claim



What I need to do is for all machines built in a given month count the number of claims within a given number of months after commissioning and the total value of the claims.





Eg



If I have a machine serial number abc123 built in jan 07 and commissioned mar 07 I need to search the table of data in group 2 for the number of claims between mar 07 and may 07 and also the total value of those claims



If you have any suggestions it would be a great help.



Thanks

Colin

Does group 2 have any date column to search within?

You will need to use a Sumproduct() based formula for multiple conditions...

e.g.

To Count

=Sumproduct(--('Table 2 sheet'!$A$1:$A$100=A2),--('Table 2 sheet'!$B$1:$B$100>=B2),--('Table 2 sheet'!$B$1:$B$100<=Date(Year(B2),Month(B2)+3,Day(B2)))

To Sum:

=Sumproduct(--('Table 2 sheet'!$A$1:$A$100=A2),--('Table 2 sheet'!$B$1:$B$100>=B2),--('Table 2 sheet'!$B$1:$B$100<=Date(Year(B2),Month(B2)+3,Day(B2)),'Table 2 sheet'!$C$1:$C$100)

Where

Table 2 sheet'!$A$1:$C$100 is the sheet and range the database is on.

Adjust ranges to suit.
