[radagast]

Hi

 

Please can some help me with the below script. It works in all browsers except IE6+

 

<script>

 

function sum(){

var form=document.getElementById('quote_form');

var rows=document.getElementById('quote_details').rows;

for (var s=[0,0,0,0,0],z0=0;z0<rows.length;z0++){

var ips=rows[z0].getElementsByTagName('INPUT');

for (var z0a=0;z0a<ips.length;z0a++){

ips[z0a].value=ips[z0a].value.replace(/[^0-9.]/g,'');

if (ips[z0a].value){

s[z0a]+=ips[z0a].value*1

}

}

}

if(form['totalmass']){

form['totalmass'].value = s[3].toFixed(2);

}

 

}

 

 

onload = function(){

sum();

}

 

</script>

 

Any help will be greatly appreciated
