各位大哥 请教一个公司网站 JS 的问题

document.writeln("<table width=\"174\" id=OnlineBox style=\"DISPLAY: none\" border=\"0\" align=\"center\" cellpadding=\"0\" cellspacing=\"0\">");
document.writeln("<tr>");
document.writeln("<td width=\"142\"><div class=\"onlines\">");
document.writeln("<img src=\"/qq/logo/topqq.gif\" width=\"142\" height=\"45\" /><div id=\"center\">");
document.writeln("<ul>");
document.writeln("<li><a title=\"内销部\" target=\"_blank\" href=\"http://wpa.在线咨询&amp;Menu=no\">");
document.writeln("<span><B>内销部QQ</B><br>1589060965</span><img width=23 height=16 src=\"http://wpa.\" border=\"0\" class=\"qq\" width=\"32\" height=\"28\" /></a></li>");

document.writeln("<li><a title=\"外销部MSN\" target=\"_blank\" href=\msnim:chat?V=1&amp;Uinssb_2323@在线咨询&amp;Menu=no\">");
document.writeln("<span><B>外销部MSN</B><br>ssb_2323@ width=32 height=28
src=\"qq/logo/msn.gif\"border=\"0\" class=\"qq\" width=\"32\" height=\"28\" /></a></li>");

document.writeln("<li><a title=\"客服\" target=\"_blank\" href=\"http://wpa.在线咨询&amp;Menu=no\">");
document.writeln("<span><B>客服QQ</B><br>1578863883</span><img width=23 height=16 src=\"http://wpa.\" border=\"0\" class=\"qq\" width=\"32\" height=\"28\"/></a></li>");

document.writeln("<li><a title=\"采购部\" target=\"_blank\" href=\"http://wpa.在线咨询&amp;Menu=no\">");
document.writeln("<span><B>采购部QQ</B><br>1335838098</span><img width=23 height=16 src=\"http://wpa.\" border=\"0\" class=\"qq\" width=\"32\" height=\"28\"/></a></li>");




document.writeln("</ul></div>");
document.writeln("<img src=\"/qq/logo/btqq.gif\"  width=\"142\" height=\"19\"/>");
document.writeln("</div></td>");
document.writeln("<td valign=middle><div><img  src=\"/qq/logo/qqtop.gif\" width=\"38\" height=\"65\" /></div>");
document.writeln("<img id=\"OnlineMenu\" src=\"/qq/logo/qqout.gif\" width=\"38\" height=\"105\" /></td></tr></table>");
document.writeln("<script type=text\/javascript>");
document.writeln("\/\/var OnlinePosition = \"left\";");
document.writeln("var OnlinePosition = \"left\";");
document.writeln("var OnlineTop = 100;");
document.writeln("\/\/var OnlineOffset = 0;\/\/如果是漂浮");
document.writeln("var OnlineOffset = -145;\/\/如果是可隐藏");
document.writeln("var OnlineSpeed = 200;");
document.writeln("<\/script>");
document.writeln("<script src=\"\/qq\/logo\/online.js\" type=text\/javascript><\/script>");

这是我们公司主页的一个JS  我就添加了一个 外销部MSN  这一栏   可是打开公司主页后看不到JS 请问是哪里出错了？
