There is, it's called javascript ;-) and for this application it should
be very easy. Something like this (not tested), or a variation:
<script type="text/javascript">
function calculateTotal()
{
var qty = document.getElementById('qty').value;
var cost = document.getElementById('cost').value;
document.getElementById('total').value = (qty * cost);
}
</script>
</head>
<body>
<form ..........>
<input type="hidden" id="cost" value="195" />
Quantity:
<input type="text" name="qty" id="qty" value="0"
onchange="calculateTotal()" />
Total:
<input type="text" name="total" id="total" value="0" />
.................
</form>
