I am using
LimeSurvey Community Edition
Version 6.5.16+240708 and I don't know what code I should write if I want to have the following filter:
Only if people choose option 1, then the next questiosn from the next group of questions will be shown.
I have tried to type Q1==1 but that doesn't work.
I tried to type this a setting for the next group of questions.
Is your first question called Q1? Is the question code of option 1 "1"?
In theory what you are posting should work, but you might do something wrong in the details. Make a copy of your survey, delete everything except the two relevant questions and then export it as LSS and upload it here for us to see what you actually did.
You are missing out quite a few details in your description.
Help us to help you!
Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).
