How to get a Numeric Stepper and sliders to work together in Flash CS4 AS3

Question

Hi I am working on a piece of coursework for school and I want to have a page where I have sliders that reflect a numeric stepper and vice versa however whenever I find a tutorial online it keeps giving me errors, the most recent of which is 1120: Access of undefined property NumericStepperEvent. I am hesitant to continue with the rest of the steppers because of the fact that I am unsure how to get it to work but I need to have this section done by Friday. Any help will be much appreciated.

Thanks Matt

You need to tell the compiler which classes to use. At the moment it has no idea what NumericStepperEvent is.

Add at the top with other imports add: import mx.events.NumericStepperEvent;

Also i'd recommend changing the argument variables written Event:SliderEvent to lowercase event:SliderEvent as this may cause another compiler error.
