Instant price quote script is working in IE but not in Firefox or Safari?

I have this script and it is performing the calculations to provide an instant price quote script fine in IE and also making only certain boxes editable when a certain radio button is clicked. However in Firefox or Safari it isn’t working.

Code:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css">

td.calchead{
width:75px;
background:none;
border-top:thin solid black;
text-align:right;
}

td.calc{
width:75px;
background:none;
border:thin solid black;
text-align:right;
}

td.products{
float:right;
text-align:right;
border:1px solid black;
}
td.inputs{
width:200px;
float:right;
text-align:right;
}

p.products{
text-align:left;
font-family:Georgia, "Times New Roman", Times, serif, 14px;
}

p.inputs{
text-align:left;
font-family:Georgia, "Times New Roman", Times, serif, 14px;
}

input.inputs{
width:30px;
background-color:CCCCCC;
}
p.calculate{
text-align:left;
font-family:Georgia, "Times New Roman", Times, serif, 14px;
}
</style>

How do I get this to work in Firefox and Safari? Why would it work in IE but not the others?
