Original pagination script

Question

This is my pagination script, and I wonder why I get these errors in IE:

function GetXmlHttpObject(){
  var a;
  try{
    a=new ActiveXObject("Msxml2.XMLHTTP");
  }
  catch(d){
    try{
      a=new ActiveXObject("Microsoft.XMLHTTP");
    }
    catch(c)
    {a=false;}
  }
  if(!a&&typeof XMLHttpRequest!="undefined")
  {
    try{
      var a=new XMLHttpRequest();
    }
    catch(d){
      var a=false;
    }
  }
  return(a);
}
var i=0;var ii=0;var b=0;var bb=0;

function ForumPagination(c){
  document.getElementById("forumsblock").style.display="none";
  document.getElementById("WaitDiv").innerHTML="<img src='images/loading.gif' >";
  xmlHttp=GetXmlHttpObject();
  if(xmlHttp==null){
    alert("Your browser does not support AJAX!");
    return;
  }
  var a="indext.php?name=Dynamic_forums&pagenum="+c;
  xmlHttp.open("GET",a,true);xmlHttp.onreadystatechange=ReplyLoading;xmlHttp.send(null);
}

function ReplyLoading(){
  if(xmlHttp.readyState==2||xmlHttp.readyState==4){
    var a=xmlHttp.responseText;
    document.getElementById("WaitDiv").innerHTML=""+a;
  }
}

script works fine in FF

btw, when I change the page, I cannot do it again.
