<!-- begin code provided by createblog.com --><br /><div id="customTen" style="display:none"><br /><table class="left" cellSpacing="0" cellPadding="4" style="display:block" width="100%" border="1"><br /><tr><th class="left" vAlign="top" align="left"><br />Last 10 Visitors<br /></th></tr><br /><tr><td class="left" vAlign="top"><br /><div id="lastTen"><br /></div></td></tr><br /></table><br/></div><br /><script>// Script by Kaiyotee<br />if(location.pathname!="/private/home.aspx"){<br />name = "";<br />navLinks = document.getElementsByTagName('a')<br />for(i=0;i<navLinks.length;i++){<br /> if(navLinks[i].innerHTML.match('xanga') && (navLinks[i+1].href.match('/private/home.aspx') || navLinks[i+1].href.match('register.aspx')) && (navLinks[i+2].href.match('logout.aspx') || navLinks[i+2].href.match('signin.aspx')))<br /> {name = navLinks[i+1].innerHTML.toLowerCase();break;}}<br />if(name=="join"){name="Guest";}<br />document.write("<SCR");<br />var time = 0;<br />document.write("IPT ");<br />document.write("SRC='http://tlog.wukm.com/tlog/track.php?view=" + name + "&offset=" + time + "'>");<br />document.write("</SCR" + "IPT>");}<br /></script><br /><!-- end code provided by createblog.com -->

from HERE

when i put the code in and look at the preview it shows up, but once i accept it and it goes onto my xanga, it won't show, why is that does anyone no?
