calculating values from select component

[Hunter Hansen]

I have a rating scale select component for 2 questions (item1, item2). the values are numbers. I want to add numbers but when I do I get NaN. Heres my javascript.

var n1 = parseInt(Appery("item1").val()), n2 = parseInt(Appery("item2").val());
Appery("totalnum").text(n1+n2);

Hi,

Your problem is that you are using the custom component. Therefore, you should use custom component name when you refer to "select" element. In other words, just replace this code:

var n1 = parseInt(Appery("item1").val()), n2 = parseInt(Appery("item2").val());

with:

var n1 = parseInt(Appery("item1_item1").val()), n2 = parseInt(Appery("item2_item1").val());
