I have two dropdown lists on my page. The first contains a list of names and the second contains a list of hardware devices.
My problem is: When i choose a name from the first dropdown i need the second to become populated with their related devices. This works fine, however if i then change the name in the first dropdown list, it adds another set of devices to the devices dropdown list.
The way i want it to work is to refresh the devices dropdown when the name is changed. So that only that persons related devices show up (in the second dropdown)
