Okay, I viewed your index.html page from your website and you have this for the code:
<script language="JavaScript" type="text/javascript">
<img src="/cgi-sys/Count.cgi?df=xuank3.dat|display=Counter|ft=6|md=6|frgb=100;151;224|dd=M">
</script>
You need to remove the JavaScript tag, it shouldn't be inside those, so REMOVE what I show in RED and it should work.
I installed the hit counter on a test page on my server to check out your problem and it works, so it should work for you after you remove the script tags.
