Excel 2007 : Finding a value based on 2 inputs

I have the below s/s

From (USD Size) To (USD Size) Security Fee (USD)
- 33 A 1
33 163 A 2
163 978 A 3
- 163 B 3
163 489 B 10
489 815 B 20

I need to return the Fee (USD) based on the Security and the range From/To. So if i have security A and size = 153 i should get 2 as the result.

Can someone help?
Thanks
Max
