LARGE Function with Conditions

Hi,

I have data arranged in columns A and B in the attached file and would like to create a formula in cell D2 that will return the largest (and the 2nd, 3rd etc largest) values from column B that are associated with AAA, CCC or DDD.

I've had a go producing at the formula but it doesn't seem to work - I would expect the answer to be 800 for the largest value and the 2nd largest would be 700.

Can someone please suggest how to fix my formula.

Thanks!
