Unity3D call function from another script (Unityscript)

I've looked up similar questions and responses and still have not been able to get this to work.

LessonRightButton.js

//#pragma strict
public var audio1 : AudioPlayback;

function OnClick(){
        var findAudioSource = GameObject.Find("AudioPlaybackButton");
        var audio1:AudioPlayback = findAudioSource.GetComponent(AudioPlayback);
        audio1.woo(); //  THIS IS LINE 50 IN THE ERROR
}

AudioPlayback.js

//#pragma strict

function woo(){
    Debug.Log("wooooooooooooooo");
}

I get this error:

NullReferenceException: Object reference not set to an instance of an object LessonRightButton.OnClick () (at Assets/Scripts/LessonRightButton.js:50)

I'm trying to call the woo function from a different script. These scripts are shortened for the purpose of ease of reading. Please advise.

you have no AudioPlayback attached on that AudioPlaybackButton object.

Either add one manually or by code:

function OnClick(){
        var findAudioSource = GameObject.Find("AudioPlaybackButton");
        var audio1:AudioPlayback = findAudioSource.GetComponent(AudioPlayback);
        if(audio1 == null){
            audio1 = findAudioSource.AddComponent(AudioPlayback);
        }
        audio1.woo();    
}
