I have the following grid:
A B C D
1 Elim Period Cost
2 0/14 6 ???
3
4 Period
5 Elim 6 12 24
6 0/7 $4.85 $6.30 $8.00
7 7/7 $4.50 $5.95 $7.60
8 0/14 $3.95 $4.75 $6.60
9 14/14 $3.55 $4.35 $5.80
10 0/30 $2.90 $3.80 $5.15
11 30/30 $2.35 $3.15 $4.15
12 60/60 $0.00 $2.70 $3.50
13 90/90 $0.00 $2.05 $2.40
14 180/180 $0.00 $0.00 $1.60


A2 and B2 are drop down lists allowing selection of Elim and Period choices.
They are both formatted as TEXT. I need to return the correct cost in C2 for
the column-row selected by Elim and Period.

I've read through other posts and it seems INDEX() or VLOOKUP() might be
what I need, but I just can't seem to make them work.

Thanks in advance for your assistance!
