Keeping track of a random default response

Francis&m — Fri, 27 Nov 2020 14:33:53 GMT

Hi,
I wrote a script to evaluate several images, 4 questions per image, I'm using survey pages. The responses is given with a slider.
I've menaged to put the sliders' default response as random, but I don't know how to keep track of the default response value effectively set.
I'd like to have a column in my data telling me which random default response was shown in each survey page.
Is it possible?

This is a part of the code:

<slider slid_aro>
/ caption = "Question?"
/ range = (1,7)
/ required = true
/ defaultresponse = list.sliderRandom.nextvalue
</slider>

<list sliderRandom>
/ items = (1-7)
/ selectionmode = random
/ replace = true
/ selectionrate = always
</list>

Works perfectly.
Thank you
