Can’t get SendMessage in webpage to send info to the web player

I am trying to get the containing webpage to send information to the unity web player with no luck.

I followed what they have here: http://docs.unity3d.com/Manual/UnityWebPlayerandbrowsercommunication.html

But I read other comments on this and found that people advise making a call to a function on the containing webpage from the web player through the start function, to make sure it’s loaded. Then I have that function execute SendMessage to send a text string back to the web player.

In the function (MyFunction) in Unity I just have it set a String variable to the text that is sent by SendMessage, then in OnGUI, I want it to display that value in a box, but I’m not able to get the value from SendMessage and assign it to the variable in my unity script.

Here is what I have:

In Unity:

myObjectScript.js ( this is attached to an object named MyObject)

#pragma strict

var myMessage : String = "testing..";

function Start ()
{
	Application.ExternalCall("DoSomething");
}

function OnGUI ()
{
	GUILayout.Box("myMessage: " + myMessage);
}


function MyFunction(param : String)
{
    myMessage = param;
}

In the html file: (See the function DoSomething at the bottom. The rest is copied from the code generated by unity for the html file.)

var config = {
	width: 960, 
	height: 600,
	params: { enableDebugging:"1" }
				
	};
	var u = new UnityObject2(config);

jQuery(function() {

	var $missingScreen = jQuery("#unityPlayer").find(".missing");
	var $brokenScreen = jQuery("#unityPlayer").find(".broken");
	$missingScreen.hide();
	$brokenScreen.hide();
				
	u.observeProgress(function (progress) {
		switch(progress.pluginStatus) {
			case "broken":
				$brokenScreen.find("a").click(function (e) {
					e.stopPropagation();
					e.preventDefault();
					u.installPlugin();
					return false;
				});
				$brokenScreen.show();
			break;
			case "missing":
				$missingScreen.find("a").click(function (e) {
					e.stopPropagation();
					e.preventDefault();
					u.installPlugin();
					return false;
				});
				$missingScreen.show();
			break;
			case "installed":
				$missingScreen.remove();
			break;
			case "first":
			break;
		}
	});
	u.initPlugin(jQuery("#unityPlayer")[0], "webcomm.unity3d");
	function DoSomething()
	{
			 u.getUnity().SendMessage("MyObject", "MyFunction", "Hello!");
	}
});

Ok I got it now. I had to move DoSomething() outside of jQuery(function() {

…

});
