for example

*table 1

A B C D
1 Start End User Rate
2 ----- ---- ----- -----
3 1.1.2000 31.12.2000 John $200
4 1.2.2001 31.12.2001 John $300


*table 2

A B C
1 Date User Rate
2 ----- ---- -----
3 3.4.2000 John ??? <--- preferred $200 as table1 "D3"

I want to get user "John" the Rate by the criteria between Start and End
from table 1, how can I do.
