Summary: I broke it.

A couple of quick things:

1. with the onclick, I think you need a semicolon at the end: "total_Prices();" . I'm not sure if its necessary, but it could be an issue.
2. I think using payment[x] is bad because it has the same format as an array. When you do ...form.payment[0].val... I believe its looking for an array. You might want to change your inputs to payment_0, payment_1, payment_2

HI,

I use this to call the following function. I had it working but somehow I broke it. I can't for the life of me see what I'm missing.

Any suggestions?

<input name="payment[0]" id="payment[0]" type="checkbox" value="15" />
...
<input id="total_amount_due" name="total_amount_due" value="" type="text" maxlength="10" />

<script type="text/_javascript_">
                       function total_Prices() {
                       var a = Number(document.request_form.payment[0].value);
                       var b = Number(document.request_form.payment[1].value);
                       var c = Number(document.request_form.payment[2].value);
                       var x = a + b + c;

                       document.request_form.total_amount_due.value = x;
                       }
</script>
