After implementing the thousand delimiter for Forms 9.2, my calculation went haywire.  Could someone take a look at the code and let me know where the issue lies?  Thanks.

$(document).ready(function () {
  $('.table').on('blur', 'input', sumtotal)
   //$('#q17').on('blur', 'input', sumtotal)
   $('#q19').on('blur', 'input', sumtotal)
    //product table function
    function sumtotal() {
      	$('.total input').attr('readonly', false);
        var quantity = 0;
      	var unit = 0;
      	var total = 0;
      	var subtotal = 0;
      	var shipping = $('#q19 input').val();
        var gradtotal = 0;
      	      
        $('.table.cf-table-block tbody tr').each(function () {
            quantity =  parseNumber($(this).find('.quantity input').val()); 
            unit = parseNumber($(this).find('.unit input').val());                    
            subtotal = parseNumber(quantity * unit);

            $(this).find('.total input').val(subtotal.toFixed(2));
            total += subtotal;
            $(this).find('.total input').change();
          
        });
          
		grandtotal = parseNumber(shipping)+parseNumber(total)//+(total*$('#q17 input').val());
		$('#q18 input').val(grandtotal);		
        $('#q18 input').change();

            
		//console.log("Total " + total);
		//console.log("Shipping " + shipping);  
		//console.log("Grand totol " + grandtotal);
    }
  

  
  	//parse for number value function
    function parseNumber(n) {
      if (typeof n === 'string' || n instanceof String)
      	n = n.replace(/,/g, '');	

        var f = parseFloat(n); //Convert to float number.     
        return isNaN(f) ? 0 : f; //treat invalid input as 0;
    }
  
	//Format numbers with commas
	$(".unit input, .etotal input, .shipping input").attr("pattern", '^(\\d+|\\d{1,3}(,\\d{3})*)(\\.\\d{2})?$');
	$(".unit input, .etotal input, .shipping input, #q18 input, .total input").on("change", function () {
		$(this).val($(this).val().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,"));
	});

});
