ActionScript is not playing the movieclip on click

Hi all,

I am sure I am doing something extremely silly, but I am unable to spot what it is...

I have created the following code in my main scene where there are no animations:

/* Interactivity Starts here */
var frequency = 3;
stage.enableMouseOver(frequency);

//BasePlate
this.basePlateBT.addEventListener("click", MouseClickBasePlate.bind(this));

function MouseClickBasePlate() {
	this.basePlateMC.play();
}

basePlateBT is the name of the transparent rectangle

This should trigger the function called "MouseClickBasePlate". I copied and pasted it every single time in the code where I needed it.

The function should play a MovieClip called "basePlateMC"

The MovieClip has several 'stops' because I need to roll out and also play other parts during other interactions, but nothing happens...

I am completely lost here... 

I would be very grateful if you could help 🙂

Thanks in advance.
