I need again help.
The question Q11 is a type of array numbers
The question Q12 is the same type.
I have a question hide with a script to charge the sum of the two variables.
Q11 -> x1
Q12 -> x2
Script -> x1+x2= y1
<script type="text/javascript" charset="utf-8">

$(document).ready(function(){
var val5 = "{INSERTANS:66315X78X9935}";
var val6 = "{INSERTANS:66315X78X9936}";
//var hola = 123;
if (val5 =="") {val5=0;}
if (val6 =="") {val6=0;}
var otro = parseInt(val5) + parseInt(val6);

// call the functions with the hidden timer question ID
runTimer(1319,otro);

function runTimer(timeQID,valor) {
$('#question'+timeQID).hide();
var fec=Date();
$('#question'+timeQID+' input.text').val(valor);
}
});

</script>
I have another similar questions, but these questions are in other page.
Q21 -> z1
Q22 -> z2
z1+z2= y1


I have a problem: y1 not updated (NaN), but if I came back previous page, y1 would update.

How could I do in order to y1 update?

Are the "val5" question and the "val6" question on a previous page? {INSERTANS} only works with questions from a previous page.

Are the SGQAs correct? Try:
Try replacing:With:
Why is "var fec=Date();" there? I see no reason for it.

Hi Tony:

Hi changed parseInt for Number and it is OK.

As var=Date() is useless.

Many thanks,

Rafael
