Public function problem

[Handycam]

In my main app, I have this button:

<mx:Button id="list2Done" label="Done" click="step2Handler()"/>

And in my component, step2.mxml, I have a public function:

public function step2Handler():void {
// called when user clicks DONE
currentState = "";
next2.enabled = true;
}
Flex Builder shows an error, undefined function. Why?

And do I need to do anything special to target next2 or the state, which are both defined in the main app?

Thanks.

This keeps happening. There's a call to a function in the main app, as above "click=step2handler()"

The step2handler code is in the script block of the step2.mxml component, as a public function.

Am I missing something? Thanks.
