Check boxes and radio buttons adding up a total

**soon** · 07:46 AM

Hi

I've got a little script that adds up values for checkboxes to give a total. I'd like to insert a couple of radio buttons in there too. I need to give them a different name to the check boxes, otherwise selecting a radio box deselects the ticks in the checkboxes.

So I currently have

Code:

<script type="text/javascript">
    function checkTotal() {
        document.listForm.total.value = '';
        var sum = 0;
        for (i=0;i<document.listForm.choice.length;i++) {
              if (document.listForm.choice[i].checked) 
{
              sum = sum + parseInt(document.listForm.choice[i].value);
          }
        }
        document.listForm.total.value = sum;
    }
</script>

<form name="listForm">
<input class="checkbox" type="checkbox" name="choice" value="4" onclick="checkTotal()">4
<input class="checkbox" type="checkbox" name="choice" value="5" onclick="checkTotal()">5
<input class="checkbox" type="checkbox" name="choice" value="10" onclick="checkTotal()">10
<input class="radio" type="radio" name="choice1" value="-20" onclick="checkTotal()">-20
<input class="radio" type="radio" name="choice1" value="5" onclick="checkTotal()">5
<input class="checkbox" type="checkbox" name="choice" value="10" onclick="checkTotal()">10

and realise that I need to change it to something vaguely like

Code:

if (document.listForm.choice[i].checked) andif (document.listForm.choice1[i].checked)
{
              sum = sum + parseInt(document.listForm.choice[i].value) + parseInt(document.listForm.choice1[i].value);

except of course that is not valid code.

Any idea what I should be putting please?

thanks

Found the answer - if anyone needs it any time:

Code:

function checkTotal() {
    var total = document.listForm.total;
    var choice = document.listForm.choice;
    var choice1 = document.listForm.choice1;
    var sum = 0;

    for (i=0;i<choice.length;i++) {
        if (choice[i].checked)
            sum = sum + parseInt(choice[i].value);
    }

    for (i=0;i<choice1.length;i++) {
        if (choice1[i].checked)
            sum = sum + parseInt(choice1[i].value);
    }

    total.value = sum;

best wishes
