The values are then passed to inputs.
I've tried this several ways ... the first question is how should such
variables be declared?

In addition to what Randy said:


[...]
function cost()
{
var cpus = form.cpu.value.slice(8,10)
var shps = form.shp.value.slice(8,10)
var total = total(cpus,wars)

Here you declare a local variable total but also want access to a
function total() (presumably declared in the global space). The local
variable masks the function, so either change the name of the local
variable, or use:

var total = window.total(cpus,wars)


or some may suggest declaring a global variable right at the start of
the script with:

<script>
var _global = this;

function cost(){
...
var total = _global.total(...)
...
}


but that seems a bit excessive here - it is unlikely a form has a
useful context to an environment that doesn't have a window object.


form.systot.value=cost(total)

Where is form declared or given a value?

<body>
<form name="price" target="paypal" action="https://www.paypal.com/cgi-
bin/webscr" method="POST">

For the sake of debugging, the action and method should be empty.
