Action Event: Sequentially enable prompting parameters

This action event disables all parameters except the first on the initial load of the prompt screen. A parameter becomes enabled once the previous one in the list has been given a value. This could be used to enforce dependencies for parameter options.

Note: In this example, the client-side javascript is in separate file to improve readability.

Global Event Type: OnChangeParameterValue

This event occurs whenever the value of a parameter is changed in the prompt screen.
