When remove the value in a field for client script onChange

[ESL]

I created a client script that calculates the sum of the values of some fields. If I put some value in thees fields, the total value is calculated immediately.
However, if I delete the value of one of the fields, the total value will not be reflected immediately, if I do not update the value of the other fields, the correct total value will not be reflected.
But when I change the value to 0 instead of deleting it, there is no such problem. Is there any workaround?

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    //Type appropriate comment here, and begin script below
    var h2 = g_form.getDecimalValue('u_float_23');
    if (h2 === '') {
        return;
    }
    var h3 = g_form.getDecimalValue('u_float_24');
    if (h3 === '') {
        return;
    }
    var h4 = g_form.getDecimalValue('u_float_25');
    if (h4 === '') {
        return;
    }
    var h5 = g_form.getDecimalValue('u_float_26');
    if (h5 === '') {
        return;
    }
    var h6 = g_form.getDecimalValue('u_float_28');
    if (h6 === '') {
        return;
    }
    var h7 = g_form.getDecimalValue('u_float_27');
    if (h7 === '') {
        return;
    }



     var total = parseInt(newValue, 10) + parseInt(h2, 10) + parseInt(h3, 10) + parseInt(h4, 10) + parseInt(h5, 10) + parseInt(h6, 10) + parseInt(h7, 10);

    g_form.setValue('u_float_21', total);
}

Insted of simply using return;

can you try

if (h2 === '') { h2=0; }

& so-on

Is because you need client script for each field where you enter decimal value.

Well you have a return if you have no decimal value, so your script will not reach the calculations because it has no value. Also, just a thought, could it be an idea to look into a calculated field instead of doing it on change? Of course only if it is a form ????
