Trying to get selectedIndex value

Below is a copy of the code that I am working.  I have looked up the selectedIndex solution in the Javascript bible and implemented within the CalcStateFee function.  Why isn't it working???


<!--Javascript section-->
function CalcStateFee(form)
{
      
      alert("passing form object into CalcStateFee")
      var result = ""
      alert("result = " + result)
      result = (FormState.VmSys.options[FormState.VmSys.selectedIndex].value)
      alert("result = " + result)
      
      var opa8 = 0;        
    var opa8um = 0;         
      var opa8l = 0;  
      var opa8lum = 0;
      var Wvoicemail = 0;
            
            if(FormState.standard[0].checked)
            {
                  opa8 = opa8 + 1
                  alert("opa8 test worked")
                  
            }
            if(FormState.standard[1].checked)
            {
                  opa8l = opa8l + 1
                  alert("opa8l test worked")
                  
            }
            
      if(document.FormState.Wvoicemail.checked)
      {
            Wvoicemail = Wvoicemail + 1
      }      
      
      
      
      //variable calculation logic
      if(opa8 == 1)
      {
            if (Wvoicemail == 1)
            {
                document.FormState.CustomerName.value="opa8um";
               alert("document.FormState.CustomerName.value= " + document.FormState.CustomerName.value)
                        //document.FormState.submit();
                return false;
        }
          else
            {
                document.FormState.CustomerName.value="opa8";  alert("document.FormState.CustomerName.value= " + document.FormState.CustomerName.value)
                        //document.FormState.submit();
                return false;
        }
      }      
      
      if( opa8l == 1 )
      {
          if (Wvoicemail == 1)
            {
                document.FormState.CustomerName.value="opa8lum";
               //document.FormState.TestCity.value=result;
alert("document.FormState.CustomerName.value= " + document.FormState.CustomerName.value)
//alert("City Code submitted to boilerplate = " + document.FormState.TestCity.value)
                        //document.FormState.submit();
                return false;
        }
          else
            {
                document.FormState.CustomerName.value="opa8l";
                //document.FormState.TestCity.value = result
alert("document.FormState.CustomerName.value= " + document.FormState.CustomerName.value)
//alert("City Code submitted to boilerplate = " +  document.FormState.TestCity.value)
                        //document.FormState.submit();
                return false;
        }
      }
