I'm trying to populate a radio button (hidSEG) question based on answers to a previous radio button (S4)
I have an equation question with the following code:
{hidSEG=if(S4.NAOK==4 OR S4.NAOK==5 OR S4.NAOK==6 OR S4.NAOK==8,1,2)}

This works in that I see the code 1 or 2 appearing in the equation question but the hidSEG question doesn't change at all.
I've been through several posts from the forum trying to do the same thing but I can't get it to work.

I'm using Limesurvey v2.73.0

Can you upload a small sample of your survey with just the relevant questions.

But the equation looks wrong to me.

I think you need to do something like {if(S4.NAOK==4 OR 5 OR 6 OR 8, hidSEG=1, hidSEG=2)}

Not tested, not sure it works, but I think the structure must be like this rather different.

Let's see if Tpartner, Joffm or Denis can come up with a working example.

If you send the sample survey, I might play around a bit when I find the time. But I am pretty sure the equation is wrong.

Thanks Holch for looking at this. I changed the equation around to match your suggestion but it still doesn't work.
Attached is a small sample with the relevant questions.

The expression in your first post is the correct format and does work except that in your equation question it is wrapped in a <p> element so it would be good to remove that.

You must understand that the Expression Manager assignment operator only manipulates questions on page load and submit so you will not see the value of "hidSEG" dynamically change as you change "S4".

See the attached sample survey:

Hi Tony,

Thanks for looking at this - I didn't realise that the hidSEG wouldn't be dynamically changed.

Cheers,
Paul

Thank you for clarifying, Tony!
