cost calculator using Javascript

Question

I am creating a cost calculator using JavaScript. I have two button in my code; clear and calculate and both work fine for the first time. However when I select different drop down menu and try to calculate again, it doesn't recalculate but same number or blank fields stay in the table.

How do I make it to recalculate? and is it possible to do this without clear button?

var settingValue;
    
    function clearForm(){
    document.getElementById("myForm").reset();
    }
    
    
    function settingValue() {
      var payment;
      var copayPerc = document.getElementById("copayPerc").value;
      settingValue = document.getElementById("Setting").value;
       payment=medicarePaymentCal(settingValue); 
       document.getElementById("medipayment").value = payment;
       document.getElementById("adj").value=seqAdjCal(payment);
    	 document.getElementById("net").value=payment+seqAdjCal(payment);
       
       document.getElementById("copay").value=payment*0.2;
       document.getElementById("actualCopay").value=payment*0.2*copayPerc;
       totalProductCost();
    }
    
    
    function medicarePaymentCal(value1) {
      var result;
      if (value1 == "Office") {
        return 1411.21;
      } else if (value1="HOPD") {
        return 500;
      }
     }
     
     function seqAdjCal(val){
      return -(0.02*(0.8*val));
     
     }
     
     function totalProductCost(){
      var applications=document.getElementById("applications").value;
      var productCost=document.getElementById("productCost").value;
      var total=applications*productCost;
     	document.getElementById("totalProductCost").value = total;
     }

Your var settingValue has same name as function settingValue.

Just rename one and should work:

  var settingValue;

  function clearForm() {
    document.getElementById("myForm").reset();
  }


  function funcSettingValue() {
    var payment;
    var copayPerc = document.getElementById("copayPerc").value;
    settingValue = document.getElementById("Setting").value;
    payment = medicarePaymentCal(settingValue);
    document.getElementById("medipayment").value = payment;
    document.getElementById("adj").value = seqAdjCal(payment);
    document.getElementById("net").value = payment + seqAdjCal(payment);

    document.getElementById("copay").value = payment * 0.2;
    document.getElementById("actualCopay").value = payment * 0.2 * copayPerc;
    totalProductCost();
  }


  function medicarePaymentCal(value1) {
    var result;
    if (value1 == "Office") {
      return 1411.21;
    } else if (value1 = "HOPD") {
      return 500;
    }
  }

  function seqAdjCal(val) {
    return -(0.02 * (0.8 * val));

  }

  function totalProductCost() {
    var applications = document.getElementById("applications").value;
    var productCost = document.getElementById("productCost").value;
    var total = applications * productCost;
    document.getElementById("totalProductCost").value = total;
  }
