Hi James,

For some reason this doesn't seem to be working. I've set all the fields I need to default to 0 when null to the css class "zero". I updated your code to the following:

// Check for null values whenever a change is made
$('.zero').on('blur','input.number',function(){
	if ($(this).val() == '')    // if the field is blank
		$(this).val(0);           // set it equal to zero
});

Is it possible that it is not taking effect because I have these fields as read only, which I also did using JavaScript?

Here is a sample of the code used for the table:

$(document).ready(function () {
    $('.cf-table-block').on('change', 'input', sumtotal);
    if ($('.subtotal').length > 0) {
        $('.cf-table-block').on('change', 'input', rowtotal);
    }
    function sumtotal() {
        var sum = 0;
        $('td.sum5').each(function () {
            var s = 0;
            $(this).find('input').each(function () {
                s += parseNumber($(this).val());
            });
            $(this).find('.subtotal input').val(s);
            sum += s;
        });
        $('.total5 input').val(sum);
    }
    function rowtotal() {
        var sum = 0;
        $('.cf-table-block tbody tr').each(function () {
            var s = 0;
            $(this).find('.sum5 input').each(function () {
                s += parseNumber($(this).val());
            })
            $(this).find('.subtotal input').val(s);
            sum += s;
        });
    }
    function parseNumber(n) {
        var f = parseFloat(n); //Convert to float number.
        return isNaN(f) ? 0 : f; //treat invalid input as 0;
    }
});

$(document).ready(function() {
    $('.sum5 input').attr('readonly', 'True');
});


$(document).ready(function() {
    $('.total5 input').attr('readonly', 'True');
});

and here is a screenshot of the form:

So I have all three fields marked as readonly. It is adding points prior and points added, and putting the total in points after. So I'm trying to make points prior equal to zero if there were no points prior. Right now it just stays blank. My process modeler kicks off a task based on their points. If they have less than 7 points to start, it does something. The problem I am having is that if the field is empty (null) the task is terminated. Perhaps there is a way to work around this in the process modeler that would be easier? You can see below that if their points prior is less than 7 and points after is greater than 7, it needs approval. This is not met if points prior is null:

Any thoughts?

Hi David, 

you can change your path condition in process modeler to following to meet the case when point prior is null. The [not(node())] will match the case when point prior is empty.

(/dataset/variable/Points_Prior_to_Incfraction[not(node())] or number(/dataset/variable/Points_Prior_to_Incfraction)<number("7")) and number(/dataset/variable/Points_after_Incfraction)>=number("7")
