Can't seem to pass variable from AS3 to Javascript

This code does not work. (Passing variable from AS3 to Javascript)

AS3 (declare variable and pass to Javascript)

var newHeight:Number = new Nubmer();
newHeight = 2;

goHeight();

function goHeight():void{
if (ExternalInterface.available){
ExternalInterface.call("funYa1()", newHeight);
}

}

In the HTML docment:

<script type="text/javascript">

function funYa1(nH) {       
alert("newHeight   " + nH);
}           

</script>

The alert says nH is undefined. Any ideas?

The alert says nH is undefined because you have braces in the call. In this case argument is not passed. Substitute the row

ExternalInterface.call("funYa1()", newHeight);

with

ExternalInterface.call("funYa1", newHeight);

and argument should be delivered to Javascript.

You have a typo in the first line 

var newHeight:Number = new Nubmer();

should be

var newHeight:Number = new Number();

Are you using swfObject to embed swf? If yes, try adding:

<param name="allowscriptaccess" value="always">

Also you could try passing a hard-coded string instead of newHeight, to see if it is a problem with the variable:

ExternalInterface.call("funYa1()", "test");

Here is a nice article about as3 and javascript communication:
