I have a web page done in dreamweaver mx (php) with 5 dependant dropdown menus.(mx widgets)

Make
Model
Spec
Job
Area

The job section has a list of Clutch, brakes, full service and so on.

Upon selecting Brakes i have a hidden multiple selection field with four options that the user can choose from.

My problem is that i only want the hidden multiple selection field to be shown when user selects BRAKES from the Job dropdown list.

I would be grateful for any help. Thanks in advance.
