Filtered dropdown list doesn't fill correctly until I click off to the side first

So, I've got a Shipping Company dropdown, it holds information like UPS, FedEx and DHL. I then have a Shipping Method dropdown, that is filtered based on the Shipping Company selection.

My problem is this. When I select a shipping company, and then try to select a shipping method, the shipping method list is either empty or filled with the filtered items from my previous selection. It only updates itself when I click off to the side of the fields so nothing has the focus, and then I bring the focus back to the shipping method field.

How do I make it so that the shipping method dropdown is updated automatically so I don't have to click off to the side to update it after I select a shipping company?

Thanks everyone,

Joanna

set the shipping method to a lookup. when the shipping company changes, it'll relookup and get the first related shipping method.
