Using the large function I can generate a list of high to low values. example:
In column E1 - E4

=LARGE(B1:B4,1)
=LARGE(B1:B4,2)
=LARGE(B1:B4,3)
=LARGE(B1:B4,4)

Next I have the names next to each value:
In column D1- D4

=INDEX(A1:A4,MATCH(LARGE(B1:B4,1),B1:B4,FALSE),1)
=INDEX(A1:A4,MATCH(LARGE(B1:B4,2),B1:B4,FALSE),1)
=INDEX(A1:A4,MATCH(LARGE(B1:B4,3),B1:B4,FALSE),1)
=INDEX(A1:A4,MATCH(LARGE(B1:B4,4),B1:B4,FALSE),1)

So if my chart was:
A B
Alpha 10
Bravo 2
Charlie 6
Delta 8

The result would be:
D E
Alpha 10
Delta 8
Charlie 6
Bravo 2

Here's my problem. Lets go back to the original chart with new values.
A B
Alpha 10
Bravo 2
Charlie 8
Delta 8

The result would now be:
D E
Alpha 10
Charlie 8
Charlie 8
Bravo 2
Which omits Deltas score.

Is there a way I can tell the index command to, if theres a duplicate value,
ignore the previous result?

Obviously this is a much simpler version than the one I have at present which
contains in excess of 70 names and results.
