Passing data to event handler function

Question

I am trying to pass value to the event handler function but I
am getting the following error. Can someone please tell me what I
am doing wrong?
1067: Implicit coercion of a value of type void to an
unrelated type function
here is the code
private function myClickListener(myid:int):void{
Alert.show("The button was clicked");
public function handleStringResult(event:ResultEvent):void{
catInfo = event.result as ArrayCollection;
for each(var o:Object in catInfo){
var b:Button = new Button();
b.label = o.FILLCOLOR;
b.id=o.CATID;
b.setStyle("fillColors",['#'+o.FILLCOLOR,'#'+o.FILLCOLOR]);
b.setStyle("color","#FFFFFF");
b.setStyle("fontFamily","Arial");
b.setStyle("fontSize",8);
b.setStyle("textRollOverColor", "red");
b.addEventListener(MouseEvent.CLICK,
myClickListener(o.CATID));
myvbox.addChild(b);

I'd change it to this:
private function myClickListener(e:Event):void{
//I don't see where you're using the ID, but to get it,
//use this code:
var myID = e.currentTarget.data;
myService.getcounties.send() // I need to send catid here to
the
webservice
public function handleStringResult(event:ResultEvent):void{
catInfo = event.result as ArrayCollection;
for each(var o:Object in catInfo){
var b:Button = new Button();
b.label = o.FILLCOLOR;
//note that you couldn't have used your ID
//as a "handle" to anything, so I replaced
//that logic with something you _could_ use
b.data=o.CATID;
b.setStyle("fillColors",['#'+o.FILLCOLOR,'#'+o.FILLCOLOR]);
b.setStyle("color","#FFFFFF");
b.setStyle("fontFamily","Arial");
b.setStyle("fontSize",8);
b.setStyle("textRollOverColor", "red");
b.addEventListener("click", myClickListener);
myvbox.addChild(b);
You could also use a Repeater and set this up in MXML.
