Well, I'm not real familiar with contentDocument but I took a shot at fixing anything I could see as not working...the only real problem I saw was when you were referencing leftline.width, you have to use leftine.style.width. here's what I came up with:

function updatetitle(){  if (ie4||ns6){    var titletext=document.getElementById("titletext");    var theiframe=document.getElementById("theiframe");    var leftline=document.getElementById("leftline");    var rightline=document.getElementById("rightline");    titletext.innerHTML=theiframe.contentDocument.title;    var titlelength=theiframe.contentDocument.title.length;    leftline.style.width= 350 - titlelength * 5;    rightline.style.width= 310 - titlelength * 5;  }}}
