Hello,

I am having a problem with an externalInterface call from a SWF to a javascript function. i am on a new Moodle 2.0 LMS which I am not too familiar with yet.

Any help would be greatly appreciated.

```auto

function reenableMainConsole():void
{
	txtErrors.text = "In reenableMainConsole function. 
";
	if (ExternalInterface.available)
	{
		txtErrors.text += "In extInterface. 
";

		try
		{
			ExternalInterface.addCallback("sidetrackStop", receivedFromJavaScript);
			if (checkJavaScriptReady())
			{
				txtErrors.text += "JavaScript is ready.
 ";
			}
			else
			{
				txtErrors.text += "JavaScript is not ready.
";
			}
		}
		catch (error:SecurityError)
		{
			txtErrors.text += "A SecurityError occurred: " + error.message + "
";
		}
		catch (error:Error)
		{
			txtErrors.text += "An Error occurred: " + error.message + "
";
		}

		function receivedFromJavaScript(value:String):void
		{
			txtErrors.text += "JavaScript says: " + value + "
";
		}
		function checkJavaScriptReady():Boolean
		{
			var isReady:Boolean=ExternalInterface.call("isReady");
			txtErrors.text += "isReady: " + isReady;
			return isReady;
		}
	}
	else
	{
		txtErrors.text += "Not in extInterface.";
	}
}

```
