Addition with Java script

I have a simple form that calculates and adds items into a "Total" field.

How do I add a fixed amount for delivery?

Here is the code for the last of twenty items and the code for the Total.

<TD align=right width="25%"><FONT face=Arial
  size=3>Professional</FONT></TD>
<TD align=right width="30%"><B><FONT face=Arial
  size=3>$435.00</FONT></B></TD>
<TD width=50><INPUT
  onchange=this.form.total.value=checkChoice(this); size=3 value=0
  name=KP price="435.00" priorval="0"> </TD></TR>
    <TR>

    <TR>
<TD width="85%" colspan="4"><B><FONT face=Arial
  size=3>Total:
  <INPUT readOnly size=12
  name=total></FONT></B>

Many thanks,

robinski

this is a javaSCRIPT question...
there must be code that updates the total value you have to modify that code so that you add the fixed delivery fee to it.. I can't figure it out from just this snippet

OOOOPS

My apology this must be the missing piece:

   <!-- Begin
   function checkChoice(whichbox) {
   with (whichbox.form) {
   if (isNaN(whichbox.value)) {
   whichbox.value = whichbox.priorval;
   whichbox.focus();
   }
   whichbox.value = Math.abs(whichbox.value);
   var dec = whichbox.value.indexOf('.', 1)
   if (dec > 0) {
   alert('No decimal places allowed for \"' +whichbox.name +'\" !');
   whichbox.value = whichbox.priorval;
   whichbox.focus();
   }
   hiddentotal.value = eval(hiddentotal.value) - eval(whichbox.price * whichbox.priorval);
   whichbox.priorval = whichbox.value;
   hiddentotal.value = eval(hiddentotal.value) + eval(whichbox.price * whichbox.value);
   return(formatCurrency(hiddentotal.value));
     }
   }
   function formatCurrency(num) {
   num = num.toString().replace(/\$|\,/g,'');
   if(isNaN(num)) num = "0";
   cents = Math.floor((num * 100 + 0.5) % 100);
   num = Math.floor((num * 100 + 0.5) / 100).toString();
   if(cents < 10) cents = "0" + cents;
   for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
   num = num.substring(0,num.length - (4 * i + 3))+','+num.substring(num.length-(4 * i + 3));
   return ("$" + num + "." + cents);
   }
   function InitForm() {
   document.myform.total.value = '$0';
   document.myform.hiddentotal.value = 0;
   for (xx = 0; xx < document.myform.elements.length; xx++) {
   if (document.myform.elements[xx].type == 'text') {
   document.myform.elements[xx].value = 0;
     }
   }
  }

   //  End -->

hiddentotal.value = eval(hiddentotal.value) + eval(whichbox.price * whichbox.value);
  return(formatCurrency(hiddentotal.value));

the above line should be changed to

hiddentotal.value = eval(hiddentotal.value) + eval(whichbox.price * whichbox.value) + 50;
  return(formatCurrency(hiddentotal.value));

where 50 is your shipping.. change it to whatever your shipping cost is
