Question

Im having a terrible time trying to calculate the value of two form fields. I’m constantly getting “NAN” which would indicate non-numeric input, this is despite the fact that the form fields are only populated with numbers.

In response I tried to use ParseInt to get a numeric value. This also fails to yield a successful result.

This is what I have so far. Any help is appreciated.

$('#value-calc input').change(function () {

    var valueINT = parseInt($('#value'),10);
    var quantINT = parseInt($('#quantity'), 10);
    var math = ((valueINT/quantINT)*1000);

    $('#cpm').val(math);
});

You need to add the .val() method after your selectors to get the value they hold
