I have a table set up to calculate the total.  seems like anything 3 digits calculates correctly except for when i enter the amount in thousands, it looks like the code drops the "0" and returns just the first digit. ie: $3000 shows an adjustment total of $3. 

$(document).ready(function() { 
  $(document).on('blur change', '.chg_amount input', sumtotal);
  
  function sumtotal() {
        var s = 0;
        $('.chg_amount input').each(function () {
            s += parseNumber($(this).val().replace('-', ''));
        });
        $('.total input').val(s.toFixed(2));
    }
    function parseNumber(n) {
        var f = parseFloat(n); //Convert to float number.
        return isNaN(f) ? 0 : f; //treat invalid input as 0;
    }
