I have included code and a copy of the form fields I am wanting to copy to other form fields and use the values in calculations.  Any advice would be appreciated.  

//Table to calculate meals estimate (var=sub;B=10,L=20,D=30)
$(document).ready(function(){
  $('.cf-table-block').on('blur', 'input', sumtotal);
  function sumtotal(){
    $('.cf-table-block tbody tr').each(function(){
      var sub = 0;
      var col1 = parseNumber($(this).find('.col1 input').val());
      var col2 = parseNumber($(this).find('.col2 input').val());
      var col3 = parseNumber($(this).find('.col3 input').val());
      sub = col1*10 + col2*20 + col3*30;
      $(this).find('.sub input').val(sub);
    });
  }
  function parseNumber(n){
    var f = parseFloat(n); //Convert to float number.
    return isNaN(f) ? 0 : f; //treat invalid input as 0;
  }
});

//Table calculation for Private Car (var=privC)
$(document).ready(function() {
    $('.mileage input').attr('pattern', '\\d{1,9}?([.]\\d{1,2})');
	$('.rate input').attr('pattern', '\\d{1,9}?([.]\\d{1,3})');
  	$('.cf-table-block').on('blur', 'input', sumtotal);
	$('.tax').on('blur', 'input', sumtotal);
	$('.shipping').on('blur', 'input', sumtotal);
    $('.mileage input').attr("step", '0.001');
    $('.cf-table-add-row').click(function(){
    $('.mileage input').attr("step", '0.001');
    });
  
	function sumtotal() {
		var sum = 0;
		$('.cf-table-block tbody tr').each(function () {
          	var privC = 0.0;
			privC = parseFloat($(this).find('.mileage input').val()) * parseFloat($(this).find('.rate input').val());
          	privC = Math.round(privC * 100)/100.0; //round to two decimal places
            $(this).find('.subtotal input').val(privC);
            sum += privC;
            //sum += parseNumber($('.tax input').val()) + parseNumber($('.shipping input').val());
            			
		});
			$('.pctotal input').val(sum);
	}
	function parseNumber(value) {
		var f = parseFloat(value); //Convert to float number
		return isNaN(f) ? 0 : f; //treat invalid input as 0;
	}
});

//Table Calculation and transTotal
$(document).ready(function () {
    $('.cf-table-block').on('blur', 'input', sumtotal);
    if ($('.subtotal').length > 0) {
        $('.cf-table-block').on('blur', 'input', rowtotal);
    }
    function sumtotal() {
        var sum = 0;
        $('td.sum').each(function () {
            var s = 0;
            $(this).find('input').each(function () {
                s += parseNumber($(this).val());
            });
            $(this).find('.subtotal input').val(s);
            sum += s;
        });
        $('.transTotal input').val(sum);
    }
    function rowtotal() {
        var sum = 0;
        $('.cf-table-block tbody tr').each(function () {
            var s = 0;
            $(this).find('.sum input').each(function () {
                s += parseNumber($(this).val());
            })
            $(this).find('.subtotal input').val(s);
            sum += s;
        });
    }
    function parseNumber(n) {
        var f = parseFloat(n); //Convert to float number.
        return isNaN(f) ? 0 : f; //treat invalid input as 0;
    }
});

//Calculate Expense totals (var=tots)
$(document).ready(function () {
	$('.sum').on('blur', 'input', sumtotal);
	function sumtotal() {
	var tots = 0;
	$('.sum input').each(function () {
		tots += parseNumber($(this).val());
		});
	$('.total input').val(tots);
	}
function parseNumber(n) {
	var f = parseFloat(n); //Convert to float number.
	return isNaN(f) ? 0 : f; //treat invalid input as 0;
	}
});

//copy fields values to other fields
$(document).ready(function () {
  alert('hello world')
  $('.sub, .transTotal, .pctotal input').on('change', function() {
    alert('hello world')
    //Meals Estimate (B/L/D)
  	$('[name="Field22(1)"]').val($('.sub input').val());
    //Private Car Mileage Estimate Total
    $('[name="Field86(1)"]').val($('.pctotal input').val());
    //Transport Estimate Total copy to Transportation
    $('[name="Field20(1)"]').val($('.transTotal input').val());
  });
});
