Javascript Chrome Help

I have some javascript code that when the person tabs from field to field it calls a javascript function that calculates a total and then updates a field (which is disabled so users can type) on the form to display the proper total. It works fine in IE. But the it does not work in chrome or firefox? Any ideas? The last line that updates the total field in the form is frm.totalbill.value = tot;

Showing your code would be more helpful.

@dadressauthorNov 07.2010 — #Thats not it as in the beginning of the function I have...

frm = document.myform;

only then am i doing...

frm.totalbill.value = tot;

@dadressauthorNov 07.2010 — #function calculatetotal()

{

var t;

var ac;

var shipping = 0;

frm = document.frmmyform;

var x=document.getElementById("damount");
  var selectedIndex = GetSelectedIndex(x.name);
 
  if ((selectedIndex == 3 || selectedIndex == 4) && !frm.shipping[1].checked)
   shipping = 5;
 
  if (selectedIndex > -1)
   t = frm.damount[selectedIndex].value
  else
   t = 0;
 
  ac = parseFloat(frm.addcookbooks.value);
  if (ac != parseFloat(ac))
  {
   ac= 0;
  }
  else
  {
   if (!frm.shipping[1].checked)
   ac = ac * (18 + 5);
   else
   ac = ac * 18;
  }
 
  ac2 = parseFloat(frm.addcookbooks2.value);
  if (ac2 != parseFloat(ac2))
  {
   ac2= 0;
  }
  else
  { 
   if (!frm.shipping[1].checked)
   ac2 = ac2 * (18 + 5);
   else
   ac2 = ac2 * 18;
  }
 
 
  var tot = parseFloat(t) + parseFloat(ac) + parseFloat(ac2) + shipping;
  frm.totalbill.value = tot;

}

@FangNov 07.2010 — #Does the select "damount" have [I]id[/I] and [I]name[/I]?

Are there any errors in the Console?

@dadressauthorNov 07.2010 — #there is no id in field just name...

no errors it just does not show the field value the rest of the javascript works fine

@FangNov 07.2010 — #This is wrong then

[CODE]var x=[COLOR="Red"]document.getElementById("damount");[/COLOR]
 var selectedIndex = GetSelectedIndex(x.name);[/CODE]

use[CODE]var selectedIndex = GetSelectedIndex('damount');[/CODE]

@dadressauthorNov 07.2010 — #Thanks so much!
