Sum of occurrences between date ranges

Hi
I need to summarize the occurrences of some risks according to the time slots below
a) less that 6 months
b) more than 6 months but less that 12 months
c) more than 12 months

I have a simple excel with a risk level and the number of days open.

I need a table that surmises the the excel I provided based on the . - I attached a sample too.

thanks

David.

Assuming you take 180 days as being equivalent to 6 months, put the following formulae in the Table sheet in the cells stated below:

B2: =COUNTIFS('raw data'!$B:$B,$A2,'raw data'!$C:$C,"<=180")

C2: =COUNTIFS('raw data'!$B:$B,$A2,'raw data'!$C:$C,">180",'raw data'!$C:$C,"<=365")

D2: =COUNTIFS('raw data'!$B:$B,$A2,'raw data'!$C:$C,">365")

then copy the formulae down to row 5.

Hope this helps.

Pete
