Comprehensive Javascript tutorial?

can you post the code, I am sure someone can chip in a tell you why it isn't working

I did make some progress today, and got part of my code working. Now I'm just trying to make it set a Storyline variable.

Here's my code that works, which embeds a Wistia video into a slide (I've remove the code to my actual video) and pops up an alert when the video completes. This code is within an object "Insert Video from Website":

<script src="http://fast.wistia.net/assets/external/E-v1.js"></script>
<iframe src="http://fast.wistia.net/embed/iframe/CodeForVideo" allowtransparency="true" frameborder="0" scrolling="no" class="wistia_embed" name="wistia_embed" allowfullscreen mozallowfullscreen webkitallowfullscreen oallowfullscreen msallowfullscreen width="640" height="360"></iframe>

<script type="text/javascript">
wistiaEmbeds.onFind(function(video) {
video.bind("end", function() {
alert("I am an alert box!");
return this.unbind;
});
});
</script>

My altered code below is supposed set my Storyline variable to "on", but my alert doesn't even fire when I have this code embedded:

<script src="http://fast.wistia.net/assets/external/E-v1.js"></script>
<iframe src="http://fast.wistia.net/embed/iframe/CodeForVideo" allowtransparency="true" frameborder="0" scrolling="no" class="wistia_embed" name="wistia_embed" allowfullscreen mozallowfullscreen webkitallowfullscreen oallowfullscreen msallowfullscreen width="640" height="360"></iframe>

<script type="text/javascript">
wistiaEmbeds.onFind(function(video) {
video.bind("end", function() {
var player = GetPlayer();
alert("I am an alert box!");
player.SetVar("EndofVideo1","on");
return this.unbind;
});
});
</script>

Is there anything obvious that I've done wrong?

Thanks,

Mike
