I need a Javascript for user entry and radio button sum

Client originally wanted sum values entered in radio boxes (at top) to be calculated in "Donation" box at bottom ("R1dollars" starting on line 392). You guys helped me with that.

Now the client has added an additional box where the donor can add an additional numerical contribution manually. (starting line 319)

We need the sum total of the manual input to appear, in addition to the sum of the radio buttons, to be calculated in the bottom Donation box (starting line 392)

As always,
thanks

     var total;
      total = getSelectedvalue('sponsorships');
      total = total + getSelectedvalue('ticketReserve');
      total = total + getSelectedvalue('programAds');
        total = total + document.getElementById('no-attend').value;
      document.getElementById('total').value = total;

Sorry, when I replace the lines of script the radio buttons still work but when I type an additional number in the "id="no-attend"  text field I get the number appended to the end of the sum and not the sum.

replace  
total = total + document.getElementById('no-attend').value;
with
total = parseInt(tota)l + parseInt(document.getElementById('no-attend').value);

Sorry, none of these solutions seem to be working. The current solution seems to have totally broken all the radio buttons. I have deleted the site and am reposting the original.

Does anyone have any ideas?

<script type="text/javascript">
function calculateTotal()
{
var total;
total = getSelectedvalue('sponsorships') + getSelectedvalue('ticketReserve')+ getSelectedvalue('programAds');

if (isNaN(parseFloat(document.getElementById('no-attend').value)))
	{
	}
else
	{
	total = parseFloat(total) + parseFloat(document.getElementById('no-attend').value);
	}
document.getElementById('total').value = total
}

then in the no-attend input box, add onchange="calculateTotal();"

Open in new window

I now realize that the solutions have not been working because as the user inputs their radio button data, and the separate numerical value, there is no "calculate" button that will create a sum for the two values.

I apologize to the people who have been giving their time to work on this issue.

I have added a line of type (line 325) "Add this amount to my total" and I have uploaded it :
http://www.littlebabyface.org/dev/reservation.html

So I will need a Javascript that will turn the line of type "Add this amount to my total" into a calculate button that will give me the sum of the radio button values to the manual input value

I am sorry that I didn't make my instructions easier.  Change your script to the following:
First change the line 323:
From
<input type="text" name="no-attend" id="no-attend" />
to
<input type="text" name="no-attend" id="no-attend" onchange="calculateTotal();" />

Then change 325:    (by the way, this link might not be understood by the users.)
From
<a href="#">Add this amount to my total.</a>
to
<a href="#" onclick="calculateTotal();">Add this amount to my total.</a>

Then change your javascript to:

<script type="text/javascript">
function calculateTotal()
{
      var total;
      total = getSelectedvalue('sponsorships');
      total = total + getSelectedvalue('ticketReserve');
      total = total + getSelectedvalue('programAds');

       if (!isNaN(parseFloat(document.getElementById('no-attend').value))){
      total = parseFloat(total) + parseFloat(document.getElementById('no-attend').value);
      }
      document.getElementById('total').value = total;
}

function getSelectedvalue(radioName){
      var radios = document.getElementsByName(radioName);
      var radioVal = 0;
      for(var i=0;i<radios.length;i++){
            if(radios[i].checked){
                  radioVal = parseFloat(radios[i].value);
                  break;                  
            }
      }
      return radioVal;
}
</script>

Thank you rstjean. I am a noob to web design and your patient help means a lot to me. I am taking your suggestion about line 325 and making the appropriate change
