    This is the code...

    <html>
    <head>
    <title>currency converter</title>

    <script language="javascript">
    <!--

    var exchRate = 1.6; // constant

    function calc(form){

    var usdValue = form.USD.value;
    var gbpValue = form.GBP.value;

    //strip dollar or pound signs:

    if (usdValue.substring(0,1) == '$') {
    usdValue = form.USD.value = usdValue.substring(1);
    }

    if ((gbpValue.substring(0,1) == '#') or (gbpValue.substring(0.1) == "£")) {
    gbpValue = form.GBP.value = gbpValue.substring(1);
    }

    if (Number(usdValue)) {
    // a number has been typed in the USD field
    form.GBP.value = ( Number(form.USD.value)/exchRate);
    return;
    }

    if (Number(gbpValue)){
    // a number has been typed in the GBP field
    form.USD.value = (Number(form.GBP.value)*exchRate);
    return;
    }

    }

    //-->
    </head>
    </script>

    <body>

    <form name="tool">
    Enter Currency to convert in desired field:

    <br>

    USD ($): <input type="text" size=8 name="USD">

    <br>

    GBP (£): <input type="text" size=8 name="GBP">

    <br>

    <input type="button" value="calculate" onclick="calc(this.form)">

    <br>

    Is the charge added on to the total, or deducted the the returned value?
