帮忙看看！那有问题，为什么不能实现计算功能呢！
这是HTML代码：
<html>
<head>
<title>计算器</title>
</head>
<script language="javascript">
var inputting="";
function inputwin(value){
inputting+=value
document.jsq.jswin.value=inputting;
}
function guiling(value){
inputting=""
document.jsq.jswin.value=inputting;
}
function hiddel(value){
if(value=="+"||value=="-"||value=="*"||value=="/"){
d=value;
document.jsq.hidd.value=document.jsq.jswin.value+"d";
document.jsq.jswin.value="";
}
}
function deng(value){
var dd;
var aa;
dd=document.jsq.jswin.value
aa=document.jsq.hidd.value
cc=eval("'aa'+'bb'")
return cc
}
</script>
<body>
<form name="jsq">
<table border="border" align="center">
