This is the question group file

This problem repeats itself no matter the question group in my survey. But doesn't appear in a new survey so I think is a general configuration issue on the survey. What could be messing around with the survey?
The same problem happens if I export and import the survey

What's the base language of your survey? I tried to import it and got an error for English, but also for Spanish.

spanish mexico

Ahhh, OK, Spanish México is not available on my installation. Just plain Spanish.

I think the problem is solved. You didn't use the array filter correctly.

In order for the array filter to work, the answer codes need to be the same for both questions.

See the attached question group.

I have this error when I eddit the question with the array filter : "Note: You can't edit the relevance equation because there are currently conditions set for this question." and I cannot change the relevance in the edit view but yes in the conditions and branching view.
is this something related with the problem?

I changed the language in the textfile to "es" and it worked: try it with plain spanish

Check my previous answer. I think the problem is related to the fact that you did not use the array filter correctly.

ahhh thanks a lot!

So does this mean it works now?
