How to access value of a variable depending on select option?

I have a SELECT option that depending on the selected value I want to change the value of a varible NumberHoliday.

How do I access the value of the variable in another function? 

var NumberHoliday;
var finalTotal;

$(function() {
  $(document).on("change", "#deptType", function(e) {
      var totalValue = $('#deptType').val();

      if(totalValue == "Fraud"){
         NumberWeekValueFraud();

      }else{
       NumberWeekValueOther();
      }

  });
});

function NumberWeekValueFraud(){
  var NumberHoliday = 25.00;
  $('#totalDays2').val(NumberHoliday);
  return NumberHoliday;
}

function NumberWeekValueOther(){
  var NumberHoliday = 50.00;
  $('#totalDays2').val(NumberHoliday);
  return NumberHoliday;
}

function CountTotal(el){
   if(el.checked) {
       //use NumberHoliday here once checkbox is check,  depending on the select option value
}

Your variable NumberHoliday is a global variable, so you can access it directly from your functions in this way:

var NumberHoliday = 0;
var finalTotal = 0;

$(function() {
  $(document).on("change", "#deptType", function(e) {
  var totalValue = $('#deptType').val();


       if(totalValue == "Fraud"){
          NumberWeekValueFraud();

       }else{
        NumberWeekValueOther();
       }


});

  });

function NumberWeekValueFraud(){
  NumberHoliday += 25.00;
  $('#totalDays2').val(NumberHoliday);
}



function NumberWeekValueOther(){
  NumberHoliday += 50.00;
  $('#totalDays2').val(NumberHoliday);
}



function CountTotal(el){
   if(el.checked) {
    console.log("Total: " + NumberHoliday);
       //use NumberHoliday here once checkbox is check,  depending on the select option value
       }
}

One workaround is to make the variable global. Another workaround is to write a separate function, in order to return the value of the variable inside the function and call it. Another workaround is to pass functions as in functional programming languages.

You can pass the function to the function

function CountTotal(el, fnValue){
   if (el.checked) {
   // do stuff with `fnValue`
   }
}


CountTotal(/* el */, NumberWeekValueFraud());


CountTotal(/* el */, NumberWeekValueOther());
