macro / selection problem

[#1]

Hi all,

I want to be able to do one things.  I am thinking a Macro might be the best way to do it.

1.   now, two listbox exist....

2.     When selecting one value in a particular list box, it activates another listbox.

3.  another listbox must to be selected ..... top one of lists

Is this possible?  I don't have the greatest fluency when it comes to macros.

help me~~
