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:
Sample survey attached:

Thank you Tony for those trick and sample,...
I'm glad to learn that this approach is fully compatible with radio type questions.
(for users needing something similar using numerical input question, there is an old discussion here )

Thanks a lot Tony. I changed Q1 into a numerical Input question and it also worked

I just noticed that the script only works when the survey Format it "Group by Group". Is there a way when survey is shown "question by question"?

I believe you can only set a list-radio with an equation question if they are both on the same page.
