I need a way to record if a participant is eligible or not based on their answers.
Ideally, a final radio button that gets selected automatically based on their previous answers. This would also be used to determine which thank you page they get sent to when they hit submit.
I am sure there is an equation that can do this but I am stumped.
I am using LimeSurvey
Version 3.17.7+190627

Basically ...(i am simplifying)
if Q1) Yes Q2) No then they are eligible and I want the radio button clicked.

You can use the Expression Manager/Script for this.

You could create this question with radio buttons and then create an equation question which will click automatically an answer in this question, based on previous responses.

Lets say you have the following questions:

Q1:
(1) Yes
(2) No

Q2:
(1) Yes
(2) No

Q3:
(1) Eligable
(2) Not eligable

Q4 (type equation) should contain something like this (not tested, just to give you an idea:

I cannot figure out what i am doing wrong. I have attached the relevant page.

Code:

{if(Q1==1 AND Q2==2, Q3=1)}

No

See manual : www.limesurvey.org/manual/Expression_Man..._Assignment_Operator

Then :
{Q3=if(Q1==1 AND Q2==2,1,Q3.NAOK)}


Else : seems you can use quota for your system, then I update the survey with a 0 quota.

It is still not auto selecting the radio button.....

It select radio buttçon when move next …
And goes to the quota out when are not "eligible"
Pregnant woman goes out by quota …

proof

And best is to read …


I think i take more time to fix your issue then you take to explain what you want …

Hi Denis,
I had downloaded your version and tested and it didn't work for me either. It always just wrote marked "A2" (not eligible) for me. But I didn't have much time to test yesterday.

Pregnant with twins or more=NO and Hairsample=YES -> A1
All other combinations = A2

Is that really the intention?
The threadstarting post with Q1..Q3 is not relating to the LSS export.
Q1 = Yes and Q2=No -> Eligable

I recommend to explain the wanted behavior with variable names of the LSS export.
And to compare the LimeSurvey versions used by everyone if not error can be found in the LSS export.
