I'm trying to sum values from an input array but the sum it keeps returning NAN

var sum = 0    //i have also tried parse(0,10);

$(qty_name).each(function(){

    var aValue = $(this).val(); //i have tried parseInt($(this).val(), 10)

    sum += aValue; //i have tried sum = parseInt(sum) + parseInt(aValue)

});

alert(sum);

i keep getting NaN. I'm coming from a php background so i've never had to deal with type casting. Please what am i missing?

That is because your other qty_name do not have perfect integer value. which results to NAN for such values. You need to parse the values to int(or float) for doing any mathematical calucations:

 var sum = 0;

 $(qty_name).each(function(){

   sum += parseInt($(this).val()) || 0;

 });

 alert(sum);
