can someone explain to me why i get an Uncaught TypeError: cannot set property of null

(function() {
        var myFunc = {
             init : function() {
                alert("I need");
                document.getElementById("myDiv").innerHTML = "help";
            }
        };
window.myFunc = myFunc;
})();
myFunc.init();

The alert() message works but the Uncaught TypeError is thrown when it reaches the next line. Can anyone explain to me why and how to fix it? I assume it is something to do with the scoping of the function as it will work if nested within the myDiv rather than the linked .js file.

Thanks

Your script is executing before the document is parsed.

You should move the <script> tag to the bottom of the document, or call init in the onload event.
