Script works in IE, but not NS or Firefox?

I made the following script to add several drop down selections to get a total and then place the total in the document.

//Calculates the total of all selections
function GetTotal()
{
    //get variables from form and makes them integers
    var Ami = parseInt(document.voting.Ami.value); 
    var Brady = parseInt(document.voting.Brady.value); 
    var Chad = parseInt(document.voting.Chad.value); 
    var Chris = parseInt(document.voting.Chris.value); 
    var Eliza = parseInt(document.voting.Eliza.value);
    var John_K = parseInt(document.voting.John_K.value);
    var Julie = parseInt(document.voting.Julie.value);
    var Lea = parseInt(document.voting.Lea.value);
    var Leann = parseInt(document.voting.Leann.value);
    var Lisa = parseInt(document.voting.Lisa.value);
    var Rory = parseInt(document.voting.Rory.value);
    var Scout = parseInt(document.voting.Scout.value);
    var Travis = parseInt(document.voting.Travis.value);
    var Twila = parseInt(document.voting.Twila.value);

  
     //adds all variables together to get total
var Gtotal = Ami + Brady + Chad + Chris + Eliza + John_K + Julie + Lea + Leann + Lisa + Rory + Scout + Travis + Twila;
           
     //makes the form element total equal to variable total
     if (Gtotal >= 110) {alert('Total can not be more than 100!');};
      else {document.voting.total.value = Gtotal};
}

Code works in IE, but not Netscape or Firefox?

This looks OK... problem is somewhere in HTML code.
