do you let your participants choose the language via a single choice question or via the language selection within the survey?
In my example, I’ll just assume that you let the participant choose the language within the survey.
[Survey menu -> Project properties -> Internal Organization -> Language selection in the survey = enabled]
In my case, German has ID 1 and French ID 2.
Create a question for the respective language within the desired page:
Within the question menu you will find the option ”Hide question, if …” in which you can set a condition to hide the corresponding question.
In this case, the hiding condition would be, for example:
For audio DE -> language = 2 (Audio DE is hidden if the language is French)
For audio FR -> language = 1 (Audio FR is hidden if the language is German)
If you let the participant choose the language via a single choice question at the beginning of your survey, you can use the variables within the single choice question (v_x) for the hiding condition.
