Please help me structure a question so that only one radio button in an array can be selected. So only one (answer option + subquestion) is allowed. For example, the question is "how many people are in the group you will be travelling with ?"
I am sure that you can do something with Javascript here.
But to be honest, I would split this up into the two questions it actually is. By the way, what if someone travels without children? (may not be relevant because it is a trip specifically with children, but I thought I mention it).

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).
