Hi,
maybe someone can be of help:

Question 1: How old are you (=numerical Input)
Question2 is a hidden question (=Radio list which should be prefilled depending on question 1.
Subquestions:
-Younger then 14 years
-14 - 19 years
-20 - 29 years
-30 - 39 years
-40 - 49 years
-50 - 59 years
-older than 59 years.

Here is the code:

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
var prev_ans = '{INSERTANS:332996X166X4102}';

if(prev_ans <= 13) {
$('#answer332996X166X36861').attr('checked', true);

}

if((prev_ans >= 14)&& (prev_ans <= 19)) {
$('#answer332996X166X36862').attr('checked', true);
}

if((prev_ans >= 20)&& (prev_ans <= 29)) {
$('#answer332996X166X36863').attr('checked', true);
}

if((prev_ans >= 30)&& (prev_ans <= 39)) {
$('#answer332996X166X36864').attr('checked', true);
}

if((prev_ans >= 40)&& (prev_ans <= 49)) {
$('#answer332996X166X36865').attr('checked', true);
}

if((prev_ans >= 50)&& (prev_ans <= 59)) {
$('#answer332996X166X36866').attr('checked', true);
}
else {
$('#answer332996X166X36867').attr('checked', true); }
;

$('#movenextbtn').click();

$('#question3686').hide();
})</script>
This code only works in Internet Explorer. The correct radion button gets checked depending on numerical input. In Firefox, Opera and Chrome always the last radio button (=older than 59 years) gets checked, regardless the numerical input.

Any idea?

Thanks
Andrea

Mind attaching a small sample of your survey with those questions?

However, if you only want to store age divided in categories in your dataset you can simply use the expression manager and question type equation

Problem solved: 'else if' instead of 'if' and it seems to work in all browsers

Yes you're right it's very easy using an equation like:
On the other hand, you may have to use another question type if you want to display the repartition by age ranges in public statistics... As far as I know, it's not possible with equation question type (quiet logical if answers are strings)

You can:
1) use a list-radio type for the the age category question
2) place it in a following group
3) set it with a following equation type question

In a simplified example, with ages from 1-10 (Q1) and 3 age categories (Q2), the equation question would look like this:
