[development] Taxonomy and input form question

[Graeme McKibbin]

Hi,
I'm quite new to Drupal and I'm doing quite a big project in it.
I'll try to keep my questions as short as I can. I wonder if anyone  
can help. This is my scenario..

I have a hierarchy something like this:

Region 1
	-- Vehicle 1
		---- Driver 1
		---- Driver 2
	-- Vehicle 2
		---- Driver 3
		---- Driver 4
Region 2
	-- Vehicle 3
		---- Driver 4
		---- Driver 6
	-- Vehicle 4
		---- Driver 7
		---- Driver 8
etc

On the submit form, I have an active select that once Region is  
selected, it filters the vehicle list, which then filters the Driver  
list
My question is, how do I add, say, a "Co-Driver" (who will be at the  
same level as the Driver)?

In other words, once someone has selected the Vehicle, I need there  
to be 2 lists (dropdowns) that are filtered with Drivers and Co-drivers.
I hope that makes sense!

Any help would be greatly appreciated. Thanks!


Kind Regards,
