Tween on CuePoint

Question

I am currently trying to create a function (or set of functions) that automatically fades in a button for each cue point in a video the first time a video loads. This way the buttons only become accessible once that point in the video has passed. The buttons should stay active once the video is loaded.
The code below is what I have so far. Essentially all I have managed to do is trace the name of the cuePoint. I believe what I need to do is somehow assign the cue point name to an object, pass that reference to the "fadeIn" function and run the "fadeIn" function.
It is worth noting that the buttons I am fading in are already on the timeline, so I do not need to create them in code. I just need to reference them.
Any and all help is appreciated!
import fl.video.MetadataEvent;
import fl.transitions.Tween;
import fl.transitions.easing.*;
promoVid.addEventListener(MetadataEvent.CUE_POINT, cueCheck)
function cueCheck(evt:MetadataEvent):void {
var cName:String = evt.info.name;
trace(cName)
function fadeIn() {
var cueTween:Tween = new Tween(--------,"alpha",None.easeOut,0,1,1,true);

Answer 1

For future reference, here is the final solution I came up with. There may be a more elegant way to do this, and if so please share it, but this worked!
promoVid.addEventListener(VideoEvent.READY, cueControls);
function cueControls(evt:VideoEvent):void {
promoVid.addEventListener(MetadataEvent.CUE_POINT, cueCheck);
function cueCheck(evt:MetadataEvent):void {
var cName:String = evt.info.name;
trace(cName)
switch (cName){
case "Conclusion" :
var cueTween9:Tween = new Tween(cluCueBtn,"alpha",None.easeOut,cluCueBtn.alpha,1,1,true);
promoVid.removeEventListener(MetadataEvent.CUE_POINT, cueCheck);
promoVid.addEventListener(VideoEvent.READY, cueControls);
case "Results" :
var cueTween8:Tween = new Tween(resCueBtn,"alpha",None.easeOut,resCueBtn.alpha,1,1,true);
case "Affordable" :
var cueTween7:Tween = new Tween(affCueBtn,"alpha",None.easeOut,affCueBtn.alpha,1,1,true);
case "Portability" :
var cueTween6:Tween = new Tween(portCueBtn,"alpha",None.easeOut,portCueBtn.alpha,1,1,true);
case "Safety" :
var cueTween5:Tween = new Tween(safeCueBtn,"alpha",None.easeOut,safeCueBtn.alpha,1,1,true);
case "Ease" :
var cueTween4:Tween = new Tween(easeCueBtn,"alpha",None.easeOut,easeCueBtn.alpha,1,1,true);
case "Innovation" :
var cueTween3:Tween = new Tween(innCueBtn,"alpha",None.easeOut,innCueBtn.alpha,1,1,true);
case "Convenience" :
var cueTween2:Tween = new Tween(conCueBtn,"alpha",None.easeOut,conCueBtn.alpha,1,1,true);
case "Intro" :
var cueTween:Tween = new Tween(introCueBtn,"alpha",None.easeOut,introCueBtn.alpha,1,1,true);
