Check your script again. I went to the page and looked at the source. The <title> is whats doing it...
The source says
<title>Using Numbers</titles>
That s at the end of the title disqualifies the closing tag. Title is one of those very few tags in HTML that absolutely has to be closed, or the entire document gets read as the title.
You need to really look at the script hard, to see what I mean, open the page, get the blank, and then view source, see what the server is sending. There is a Javascript after the closing html tag thats partial, etc..
Try fixing the closing title tag, it should work.
