Me imprime variable en expolrer pero no en firefox

[portillo18]

Bueno dias a todos:

Tengo un problema a la hora de imprimir una variable asp en html.
Mi código es el siguiente:

<input type="hidden" value=<%=Application("contador")%> name=numeral size="10" onKeypress="if (event.keyCode<48 || event.keyCode>57) event.returnValue=false;" onblur="this.setAttribute('value', this.value);" maxlength="10">

El imput me manda la variable de session a una funcion donde transformo un nº en nº romano, la funcion es la siguiente:

function romanise(){

var persian=numeral.value;
var roman="";
var ronumdashes="";
var buffer=10-persian.length;

while (buffer>0) {persian="0"+persian;buffer--}

var units=new Array("","I","II","III","IV","V","VI","VII","VIII" ,"IX");
var tens=new Array("","X","XX","XXX","XL","L","LX","LXX","LXXX" ,"XC");
var hundreds=new Array("","C","CC","CCC","CD","D","DC","DCC","DCCC" ,"CM");
var thousands=new Array("","M","MM","MMM","MV","V","VM","VMM","VMMM" ,"MX");
var billionsdashes=new Array("","=","==","===","==","=","==","===","====" ,"==");

romandashes=billionsdashes[persian.substring(0,1)];

var hundredmillionsdashes=new Array("","=","==","===","==","=","==","===","====" ,"==");

romandashes+=hundredmillionsdashes[persian.substring(1,2)];

var tenmillionsdashes=new Array("","=","==","===","==","=","==","===","====" ,"==");

romandashes+=tenmillionsdashes[persian.substring(2,3)];

var millionsdashes=new Array("","_","__","___","_=","=","=_","=__","=___" ,"_=");

romandashes+=millionsdashes[persian.substring(3,4)];

var hundredthousandsdashes=new Array("","_","__","___","__","_","__","___","____" ,"__");

romandashes+=hundredthousandsdashes[persian.substring(4,5)];

var tenthousandsdashes=new Array("","_","__","___","__","_","__","___","____" ,"__");

romandashes+=tenthousandsdashes[persian.substring(5,6)];

var thousandsdashes=new Array("","","",""," _","_","_","_","_"," _");

romandashes+=thousandsdashes[persian.substring(6,7)];

roman=thousands[persian.substring(0,1)];

roman+=hundreds[persian.substring(1,2)];

roman+=tens[persian.substring(2,3)];

roman+=thousands[persian.substring(3,4)];

roman+=hundreds[persian.substring(4,5)];

roman+=tens[persian.substring(5,6)];

roman+=thousands[persian.substring(6,7)];

roman+=hundreds[persian.substring(7,8)];

roman+=tens[persian.substring(8,9)];

roman+=units[persian.substring(9,10)];
//este br iria romandashes+"<br>"+roman;


var result = romandashes+roman;
document.write(result);
}
</script>

El resutado de la variable me lo da perfectamente, ahora bien el problema lo tengo al imprimirlo desde html, de la siguiente manera:

<td><img src="udjat.jpg" width="18" height="18">&nbsp;<script language="JavaScript" type="text/javascript">romanise()</script>&nbsp;<img src="udjat_2.jpg" width="18" height="18"></td>

El caso esque me funciona a la perfección el internet explorer pero no en firefox, es urgente por favor!


de antemano gracias!
