有关JS循环的问题？

Question

function s(){ 
var $ = document.form;
var count = document.form.gamount.value;
for (var i=1;i<count;i++){
var a = $.count_1_+i;
var b = $.prod_price_+i;
var c = $.cp3_+i;
var d = $.cp4_+i;
var e = $.sid_+i;
if(e.value=="1"){
c.value = 0;
d.value = Number(a.value)*Number(b.value);
}else{
c.value = Number(a.value)*Number(b.value);
d.value = 0;
}
}
}麻烦高手看一下上面的代码是什么问题？我为什么运行报错，执行不了！在线等！谢谢

var a = $.count_1_+i;
var b = $.prod_price_+i;
var c = $.cp3_+i;
var d = $.cp4_+i;
var e = $.sid_+i;
if(e.value=="1"){
c.value = 0;
d.value = Number.valueOf(a.value)*Number.valueOf(b.value);
}else{
c.value = Number.valueOf(a.value)*Number.valueOf(b.value);
d.value = 0;
}
}
}

var d = $.cp4_+i;
var e = $.sid_+i;
if(e.value=="1"){
c.value = 0;
d.value = parseInt(a.value)*parseInt(b.value);

if(e.value=="1"){
c.value = 0;
