I am using LimeSurvey version 2.05.

Some of my questions are multiple choice and though I want to show them all the options, I want to circumvent the participant selecting two opposing answers.

For example,
a - I already knew about X
b - I did not know about X
c - I was completely involved in X
d - I was only partially involved in X
e - I suffered because of X

What I need is not only an exclusive option (turned on for B.) but also an IF A is selected THEN B cannot be selected. I have a few longer (up to 20 choices) multiple choice question with a similar scenario. IF A is selected THEN B cannot be or even IF C is selected then D cannot be selected but they can select more from the rest of the list.

I hope this makes sense. Any help is greatly appreciated.

Hi, nique,
did you read and try

Hi Joffm,

Thanks for that. No idea how my searches didn't pick up on it.

I am happy to use that question validation however I guess I am after something more like the exclusion. Rather than prompting the participant to the two options that cannot work together, I would like to have it such that if they select C, B is greyed out. Similar to the exclusive option.

Is that at all possible or too much?

Thanks for your help!

Hi, nique,
therefore I asked "Did you try?"

In Tony's example the respondents are not prompted, no, after checking "option 1" the opposite ("option 2") isn't displayed, it just disappears.
And viceversa - as you like.
Please see screenshot.

Well, graying might be possible with JS but why not use this easy built-in feature.

Hi, nique,
just to add something:
1. I missed that you work in LS 2.05. Regarding Tony this relevance only works in 2.06 and higher.
So maybe you could update to 2.06 to be able to keep your templates.

2. You surely have some reasons to design this question this way.
But let me ask:
Why isn't it sufficient to only have the answer option "Do you know...?"
Either the respondent checks if he knows, or does not check if he doesn't know.
Now there are two answer options which cannot be checked both.
And some respondents will think "What a stupid questionnaire".

What about a respondent who neither checks "I know" nor "I don't know"?
So you have to check that each of these alternative pairs contain an answer.
And what does a respondent check (c and d) who isn't involved at all?

Can't you change the design of this question to a matrix with answer options "Yes" and "No"?
Then it is IMHO sufficient to ask "Do you know...?"
And you will have an answer for each question.

Best regards

Hi Joffm,

Okay. I won't be able to make this work in 2.05.

Thanks for your help anyway.
