Hi!

I'm trying to find a way to set relevance condition to skip a question if it was already answered for the token.
For example: token 111 first enters the survey and sees question Q1. He enters the answer and finalizes the survey. Next time he enters the same survey using the same token question Q1 needs to be hidden as already answered.
I tried to set relevance condition for Q1 as is_empty(Q1.NAOK) but due to Dynamic changes I can't even enter the answer as it disappears. Same goes for count(Q1.NAOK)==0 condition.

What condition should I use? Or maybe there is a way to disable Dynamic On-page relevance?

Have a look here

Thanks, that helped. But it's a really uncomfortable workaround. It would be really helpful if non-relevant questions saved data instead of changing it to NULL.

See "$deletenonvalues" in config.php - www.limesurvey.org/manual/Optional_settings#Survey_Behavior

That partially worked. I received very strange results of computation:

I have equation question
EQ1= {if(is_empty(Q1.naok), 1, 0)+if(is_empty(Q2.naok), 1, 0)+if(is_empty(Q3.naok), 1, 0)}
and three questions with relevance conditions:
Q1: EQ1=
Q2: EQ1==2
Q3: EQ1<2

I need to show next of Q1-Q3 each time token enters the survey.
Now is works 1st and 2nd times, but after that EQ1 fixes on value 2 and never changes again. I have a suspicion that after second entry with same token equation questions just stop any calculations. But how to fix it haven't got a clue.

Put a +1 on this Feature request : bugs.limesurvey.org/view.php?id=9110

Now it is not a question of multiple token uses but a question of why equation calculation stops working after first completion and is there a way to jump start it again.

+ : it's unsure : it can be concat or sum.

Better is to force count here:

Or maybe here:

Yep, tried that already. The same story. The equation stops calculating results on second entry. And then you get stuck on same step - when there are answers to Q1 and Q2, but EQ1= {if(is_empty(Q1.naok), 1, 0)+if(is_empty(Q2.naok), 1, 0)+if(is_empty(Q3.naok), 1, 0)} (or EQ1= 3-count(Q1.NAOK,Q2.NAOK,Q3.NAOK)) is stuck on the value of 2 and never changes.

Can you upload a little lss file or a lsa file to make some test ?

Here it is. $deletenonvalues is set to 0.
