    Question help! object error with onchange()

    hi, i am frustrated with this error. the script works fine if i don't loop php for the links i need, but i kinda need to use the php loop.

    The error line is in bold red when i try to execute it (click on the link).

    in the head:
    Code:
    <script type="text/javascript">

    var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
    var loadedobjects=""
    var rootdomain="http://"+window.location.hostname
    var bustcacheparameter=""
    
    function ajaxpage(url, containerid){
    var page_request = false
    if (window.XMLHttpRequest) // if Mozilla, Safari etc
    page_request = new XMLHttpRequest()
    else if (window.ActiveXObject){ // if IE
    try {
    page_request = new ActiveXObject("Msxml2.XMLHTTP")
    } 
    catch (e){
    try{
    page_request = new ActiveXObject("Microsoft.XMLHTTP")
    }
    catch (e){}
    }
    }
    else
    return false
    page_request.onreadystatechange=function(){
    loadpage(page_request, containerid)
    }
    if (bustcachevar) //if bust caching of external page
    bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
    page_request.open('GET', url+bustcacheparameter, true)
    page_request.send(null)
    }
    
    function loadpage(page_request, containerid){
    if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
    document.getElementById(containerid).innerHTML=page_request.responseText
    }
    
    function loadobjs(){
    if (!document.getElementById)
    return
    for (i=0; i<arguments.length; i++){
    var file=arguments[i]
    var fileref=""
    if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding
    if (file.indexOf(".js")!=-1){ //If object is a js file
    fileref=document.createElement('script')
    fileref.setAttribute("type","text/javascript");
    fileref.setAttribute("src", file);
    }
    else if (file.indexOf(".css")!=-1){ //If object is a css file
    fileref=document.createElement("link")
    fileref.setAttribute("rel", "stylesheet");
    fileref.setAttribute("type", "text/css");
    fileref.setAttribute("href", file);
    }
    }
    if (fileref!=""){
    document.getElementsByTagName("head").item(0).appendChild(fileref)
    loadedobjects+=file+" " //Remember this object as being already added to page
    }
    }
    }
    
    </script>

    in the body:
    Code:
    <form>
    <select id="ajaxmenu" size="4" onChange="ajaxcombo('ajaxmenu', 'contentarea')">
    <option value="">Select A file to load</option>
    <?
    include("db_connection.php");
    $sql = mysql_query("SELECT sp_id, sp_company FROM companies WHERE sp_accepted = 'Y'") or die(mysql_error());
    	while ($row = mysql_fetch_array($sql)) {
    		$spid = $row['sp_id'];
    		$spcompany = $row['sp_company'];
    		echo "<option value=\"getpage.php?sid=$spid\">$spcompany</option>\n";
    	}
    ?>
    </select>
    </form>
    <div id="contentarea"></div>
    any thoughts on generating the options for the select with php would cause this error? whitespace?

    thanks.
