javascript functions fra html

Jeg har det her kode, og jeg fatter simpelthen ikke hvad jeg har gjort galt ... sikkert en eller anden lille åndsvag ting :) men jeg kan stadig ik finde den ...


<HTML>
<HEAD>
<SCRIPT type="text/javascript" language="javascript">
function focu(x,e) {
    return (1/2)*Math.pow(2*x-1,1+2*e)+(1/2);
}

function resource(oq,sr,ma,ut,n) {
    return Math.pow(3*focu(oq/1000,1)+focu(sr/1000,1)+focu(ma/1000,1)+focu(ut/1000,1),2) * Math.log(n) / Math.log(5000) / 13.307904;
}

function calc() {
    int oq = document.resource.oq.value;
    int sr = document.resource.sr.value;
    int ma = document.resource.ma.value;
    int ut = document.resource.ut.value;
    int n = document.resource.n.value;
   
    int cpu = Math.floor(resource(oq,st,ma,ut,n)*10)/10;
    int total = cpu*n;
   
    document.resource.cpu.value = cpu;
    document.resource.total.value = total;
}
