I have a value range that I would like to return a single number for. This
is the table I have in excel.

A B C
1 10 21 15
2 21 31 25
3 31 41 35
4 41 51 45
5 51 61 55
6 61 71 65
7 71 81 75
8 81 91 85
9 91 101 95
10 101 111 105
11 Results
12 52.95
13 55.84
14 56.18
15 54.67
16 50.00
17 52.95
18 57.10


I would like to calculate if a result falls between the data in column A and
B it shows column C. I.e. if the number is 52.95 (A:12), in the cell next to
it (B:12) would be displayed 55.
