ExternalInterface Issues

Question

JS Code:
function iclicked()  {
     var myFlashMovie = document.getElementById("flashID");
     myFlashMovie.javaFn();
AS3 Code:
ExternalInterface.addCallback("javaFn", flashFn);
function flashFn()  {
    // Do this
The problem is that with this code, I receive an error that says javaFn is not a function.
I was researching and I read that the problem may be that there may not have been enough time for it to completely load but I doubt that is the problem.
I am willing to try this solution but how would I go about not going any farther, until five seconds have passed by?
Are there any solutions out there?

Answer 1

I changed the JS to:
function iclicked()  {
     var myFlashMovie = window.document.flashID;
     myFlashMovie.javaFn();
I am still getting the same error.
I can't even do, "myFlashMovie.play()".
