Why doesn't this javascript function work to display this:

PHP Code:
<script language="JavaScript"> var strCode '';</script>
<script src="http://www.test.com/webmaster/newsbox/webmaster.php?target=&prefiximage=&prefix=on&style=&color=%23000000&font=Verdana&size=0&top=17&category=1&ReturnAs=html"></script>
<script language="JavaScript">document.write(strCode);</script> 
Can you see any problems with the javascript "code"?
