Sorry for the confusing post. The value in column D is only indirectly
related to my request. I had previously sorted the range A3:D60000 descending
by column D so that the values in D go form high to low.
That being said your formulas did provide a means to the answer I was
looking to find.
Thank you.

I have a data set from A3 to D60000.
In any selected row the data values in columns A, B and C correspond to a
value in column D.
Eg. If A4=1.04, B4=.96 and C4=.75 then the value in D4= 25

I have a similar data set F3 to I60000.
Similarly in any selected row the data values in columns F, G and H
correspond to a value in column I.

I need a lookup or reference formula such that I can find the value of
column I for the data group in columns A, B and C. I.e. if I reference
A9847, B98847 and C9847 the formula would find the value in column I that has
those same data values.

I know similar questions have been posted before and I tried to adapt those
answers to my problem but couldnt get a working formula.

I can't see what the information about D4 has to do with the problem.
If you are looking for the value in the I column that is on the same
row as the three data in columns F,G,H that are equal to the three
data in columns A,B,C (but on another row) this is one way to go.
I assume that column E that has not been mentioned is free to use as a
helper column,
In cell E3 enter
=F3&G3&H3
copy down as far as you have data in columns F,G,H,I

The result I put in column J (which is the first free column)
In cell J3 enter
=VLOOKUP(A3&B3&C3,E$3:I$1000,5,FALSE)
change 1000 to the last row with data in columns F,G,H,I
copy down as far as you have data in columns F,G,H,I

If the three data A,B,C are not present anywhere in columns F,G,H
the result in column J will be #N/A.

Hope this helps / Lars-Åke
