Script solo se muestra una vez. por favor.

[rubenpm21]

Buenas a todos, he seguido este foro durante tiempo y siempre he encontrado la respuesta por lo que nunca me ha hecho falta pediros ayuda personalizada, pero ahora se me plantea un dilema. Tengo un script que coge el texto de un .txt externo pero resulta que al poner varias veces el script (la variable que indica el .txt que quiere mostrar)solo inicia el primero y el resto aparece un texto de "inicializando" y no hace nada.

Este mi codigo html:

Código HTML:

<script src="js/ajaxtickerfijo.js" type="text/javascript"></script>

<div id="newizq"><script type="text/javascript">
var xmlfile="noticiasprincipal/noticia1.txt" //este es el archivo que coge
//ajax_ticker(xmlfile, divId, divClass, delay, optionalfadeornot) new ajax_ticker(xmlfile, "ajaxticker1", "someclass", [3500], "fade")
</script></div>///este codigo se repite pero solo muestra bien la primera el resto no

El script es este:

function createAjaxObj(){
var httprequest=false
if (window.XMLHttpRequest &&!window.ActiveXObject){ // if Mozilla, Safari etc
httprequest=new XMLHttpRequest()
if (httprequest.overrideMimeType)
httprequest.overrideMimeType('text/xml')
}
else if (window.ActiveXObject){ // if IE
try {
httprequest=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e){
try{
httprequest=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e){}
}
} //end IE
return httprequest
}

this.tickerid=divId //ID of ticker div to display information
var delay=(typeof delay=="number")? [delay] : delay //convert parameterif string into array [delay, refetchdelay]
this.delay=delay[0] //Delay between msg change, in miliseconds.
this.refetchdelay=delay[1] //Delay between refetching of Ajax contents
this.mouseoverBol=0 //Boolean to indicate whether mouse is currently over ticker (and pause it if it is)
this.pointer=0
this.opacitystring=(typeof fadeornot!="undefined")? "width: 100%; filter:progid:DXImageTransform.Microsoft.alpha(opa city=100); opacity: 1" : ""

Os agradezco mucho la ayuda estoy desesperado y me es de vital importancia

Bueno pues ya está lo he conseguido así que se puede cerrar el tema. Quiero agraceder al foro su labor porque aunque esta vez la ayuda no ha sido directa, otras muchas veces he cogido las soluciones directamente de otros post. Gracias.
