Hello,

I'm trying to make a text display that dynamically show answer from previous equation type question.
The equation type questions itself is a calculation of previous single choice type question.

Example:

Question1 (single choice): select a number from choices below.

• A1 = 5
• A2 = 10

Question2 (equation): {Question1.shown*2}

Question3 (text display): This is your Question1 answer times 2: {Question2}

The problem is, the text display won't update after the user answer Question1 unless I add another Question4 and modify Question3 like so:

Question4 (long free text): Type anything

Question3 (text display): This is your Question1 answer times 2: {Question2} and this is Question4 value: {Question4}

The text display itself won't update after the user answer Question1. But it will update after the user answer the Question4.

This is only happens in LimeSurvey 3.

I attached an example survey.

Is the attached file the correct one? Perhaps I don't understand your post.
The survey structure seems to differ.


What exact version of LS 3 is used?

Yes, the attached file is different than the one I wrote in question, sorry for that (I don't know how to explain).

Here I attached the correct one:

This is what I meant:

Picture 1:
A. The user answered 5 as Question1.
B. Question2 becomes 10. But in Question3, the {Question2} field is still 0.


Picture 2:
A. The user answered Question4. The Question3 display the {Question4} field correctly.
B. The {Question2} field in Question3 also changed to 10.


Somehow, the {Question2} field in Question3 only updates after the user answer Question4. If I remove the Question4 and the {Question4} field in Question3, the {Question2} field in Question3 will never updates.

I'm using version 3.2.0+180206, but I encountered this since 3.0.0. This doesn't happens in 2.73.0.

Ok. That issue can be seen in the first survey too.
The reference to the result of the equation-question is empty till another update is triggered.
I was able to reproduce this issue on demo.limesurvey.org (3.1.1).
Do you want to open a bugreport?

Thank you! That is exactly what I meant.

I don't know how to explain a bug report.
That is why I posted here so maybe someone can make a bug report with better explanation than me.
