Hi, we are about to start a new study with international group.
Each country will collect their data, project leaders using Qualtrics. They want age verification at the first screen. Here what they wants

Participants will first see a screen of questions to check for eligibility when they go to the survey website. If a participant is underage, a thank you screen will subsequently greet him or her and say Goodbye. If not, a click of OK will turn over the page to the study information screen.

How can I do smth like that with LS.

Maybe with conditions I can solve it. I will ask age in the first question then if he or she under 18 go to the end, but how…
Could you show me a way
Thanks in advance

Use a quota.

If you ask age in a list(radio) like
1: under 18
2: 18-25
3: ...
you can use the quota directly

If you ask the real age in a numerical input
you have to create an equation like {if(age<18,0,1)}
and set the quota on this equation.
