I want to crate a pull down menu based on the value from another pull down
menu. E.g.
If I select 1 from the first pull down menu then the values X,Y,Z
(corresponding value associated with 1) would be in another pull down in a
different location.

1st Pull down Values 2nd Pull down Values

1 X,Y,Z
2 A,B,C
3 E,F,G
4 O,P,Q
