Using a list box to perform lookups on a table

In archery there are a number of different rounds shot (about 60).

A particular score on a round results in a handicap rating.

I have been trying to enter the score and the round shot (from a list box) and use a VLOOKUP to establish the handicap from a table.

I can't figure out how to do it! How to make the table array a variable which can change according to the selection in the list box

I have achieved the result I need in other ways on a small scale by having large nested IF statements based on the round name but there is a point when the formula gets too big.

Can anyone help? Or can anyone come up with a macro to do it?

I have attached a very simple example.

Thanks
