How to assign value to a second combobox with reference to first combobox?

Here's a good article on Dynamic Options with JavaScript at http://www.quirksmode.org/js/options.html. This will help you populate the second combo box, just use the data from the first combo box to drive your options in the second one. If you have a lot of options to load you can also use Ajax to dynamically load the combo box.
