Second list box values changing according to selection of first list box

Hi

I have simple table that lists cars, trucks etc. I would like to put those values to list box. And I want to have another list box as well. If user selects cars, it will go to another table and read cars there and list them at second list box. If user select trucks, it will automatically select trucks from table and list them at second list box.

If you could please help, it will be great.

Thanks
