Thanks Tom,

That has Made it Clearer.
So Basically, if rng was say D5 :-
rng(1,1) would be D5
rng(1,0) would be C5 &
rng(1,-1) would be B5.
I am Still Unclear though what the "+ i" in rng(2 + i, 1) & the "+ 1" in
rng(2 + 1, 1) Actually Does.
Also, what Does the ? Do Please.

Thanks in Advance.
All the Best.
Paul
