Help Requested - Simple If Statement Error Fix

Hi there - I suspect I’m doing something silly here. Keep getting a #1009 error pointing towards the fadeOut function on frame 2. Here’s the scoup, TIA!

Frame 1: Clickable Logo that sends the playhead to frame 2

import flash.display.StageDisplayState;
stage.displayState = StageDisplayState.FULL_SCREEN;

stop();

esLogo.buttonMode = true;
esLogo.addEventListener(MouseEvent.CLICK, onClick);

function onClick(e:MouseEvent):void
    {
        gotoAndPlay(2,"intro");
        trace("onClick");
    }

Frame 2: fade the logo out until you get to the other stuff


// esLogo.removeEventListener(MouseEvent.CLICK, onClick);
// var esLogo:MovieClip = new MovieClip;

esLogo.addEventListener(Event.ENTER_FRAME, fadeOut);
function fadeOut(e:Event):void
{
    if (esLogo.alpha <= 1)
    {
        esLogo.alpha -= .1;
    }    
    
    if (esLogo.alpha <= 0)
    {
        esLogo.alpha == 0;
    }
}
