I have already used the iframe tags with no luck, it just plays in a separate window instead of on the page. I got a tip to use the div tags to create a swiffy container then this code at the end of the body tag.
<script>
var stage = new swiffy.Stage(document.getElementById('swiffycontainer'),
swiffyobject, { });
stage.start();
</script>
This does not play on the page and I get a 404, but if I type in the path to the swiffy file, it plays in a separate window.
