Hey! I am conducting a Van Westendorp Pricing Study on the platform, and when someone answers the four questions regarding what they consider "cheap," "ideal," "expensive," and "too expensive" without logic (for example, the "too expensive" value being lower than the "cheap" value), a message appears asking them to use the Back Button and re-enter the information. However, the Back Button option does not appear (please see the screenshot attached), only the Next button. Could you please help with this?
Thanksss

To show the Back Button only on specific pages (e.g., when illogical input is detected), you can use custom JavaScript.
Add JavaScript: In the Look & Feel section (or under Question Settings > Add JavaScript), add this code:
And I only have question in one block. The other blocks are from the Van Westendorp Pricing model
I don't need the Back Button on the entire questionnaire. It's only necessary on the page where it shows that the respondent entered the prices illogically. That way, if I only manage to insert the Back Button on that page (so the respondent can correct the values), I would already be very satisfied. A curious fact is that it was showing up, but after a few more tests, it stopped appearing.
