problem calling skin using swfobject

I'm trying to use a skin and am having trouble with where to put the code to get it to load. Here's the code I'm using to embed the default player, which works fine:

src="http://videomi.com/swfobject.js"></script>

<div align="center">

<script src="http://videomi.com/swfobject.js"></script>

<script type="text/javascript">

var player = null;

function playerReady(obj)
{
player = document.getElementById(obj.id);
};

var flashvars =
{
file: "http://videomi.com/videos/StMein_Welcome/StMein_WelcomeFinal_H264_512x288.mp4",
id: "player1",
autostart: "false"
};

var params =
{
allowfullscreen: "true",
allowscriptaccess: "always",
wmode: "transparent"
};

var attributes =
{
id: "player1",
name: "player1"
};

swfobject.embedSWF("player.swf", "placeholder1", "432", "344", "9.0.124", false, flashvars, params, attributes);

I've tried putting it with the var flashvars =, I've tried putting it with the var params =, and nothing seems to work. This is the format I'm using, which matches the other variables, which do all work correctly.

skin: "http//www.path/nacht.swf

Any help appreciated.
