Hi, I m searching an answer from a few hours to my problem...

I have 2 array questions (numeric value) , let's say Q1 and Q2

I have a Q3 question wich is radio button type (two answers A1 and A2)
I d like to check automatically :
- A1 if (({Q1.NAOK}/{Q2.NAOK}) < 0.1)
- A2 if (({Q1.NAOK}/{Q2.NAOK}) > 0.1)

I m going to try to do it following this workaround.
www.limesurvey.org/manual/Workarounds:_M..._.28default_value.29

My problem is I d like the answer to be locked (the user can't modify it - indeed, I use this answer to calculate some equation questions)
Just beginning with limesurvey and maybe my reflexion is not good.

Thanks a lot for your help.

You can punch(set) an answer option with EM but you would need some javascirpt to disable it.

BTW, the questions punched via EM can be made hidden from questions setting and can be used later in survey for calculations.

Be careful when disabling radio inputs - that may prevent the data from being recorded.

Why not load the value into a hidden equation question instead of using radios?

Thanks for your both answer...
You're right it wasn't a good solution, and not useful...

I just add in my question a condition to display a text, as this :
and it feets perfectly to my needs.

I will just have to change the calculation of my equation questions.
Thanks again.
