browser to unity communication

I am having some problems sending anything to my gameObject from the browser

Here is the browser code in the body
<input type=text id="sendme" value="hello">

Here is the browser code in the script section
function sendToUnity(){
sendthis=document.getElementById("sendme").value
getUnity().SendMessage("CSB","MyFunction",sendthis);

}

function fromUnity(data){
eval(data);
}
</script>

And on the unity side I have
CSB is a game object
attached is a script called worldsetup.js
and inside that is


function MyFunction(arg:String){
Application.ExternalCall ("fromUnity", "alert('Hello from Unity')");
}

The call in MyFunction works fine outside of MyFunction..so it's not that.
I don't think the call from the browser to Unity is working but I'm not sure why.
I'm using Firefox

Thanks,

Dan

 

I was using getUnity instead of
GetUnity()

works now.
