Problem With Handling arrays/JavaScript

Hai Friends,

I have a table having 4(DropDownBoxes)columns that grows dynamically.

In the first column I want a Combo Box to populate all National Regions from
the database.

Upon changing a National Region, I want to populate all States pertaining to
the selected National Region in another Combo Box beside the first one from
the database.

Like wise, Upon changing a State, I want to populate all Counties pertaining
to the selected State in another Combo Box beside the Second one from the
database.

The Last column will have a hyperlink to the same page with "Delete" as
text display.

I have a Command button (Add New Location) upon clicking should grow the
table by adding a new row with another set of the elements (one combo box
each for National Regions, States, Counties) and a Delete hyperlink.

I want to delete a particular set (row) of elements by clicking the Delete
hyperlink.

The functionality should be such that only that particular set of elements
(their values) should disappear and the total number of rows should get
reduced by one and all the other elements should have their values intact.

How can I achieve this functionality?

Using Arrays and with

JavaScript or

ASP voding
