==================Dear Community,I am developing a survey where I need respondents to access certain sections based on a time constraint. Specifically, I want respondents to complete a set of pre-treatment questions, undergo a treatment, and then complete additional questions after a delay.Here's what I’m aiming to achieve:

1. Single Link Access: Respondents should access the survey through a single link.
2. Initial Questions: They should first answer a few pre-treatment questions.
3. Time-Based Access: After completing the initial questions, they should receive a message indicating that the next part of the survey will become available in 20 minutes.
4. Visibility Control: After the 20-minute delay, the subsequent part of the questionnaire should automatically become visible on their page.

I attempted to use HTML and JavaScript in the End Message section of the survey but didn’t achieve the desired result. As I’m not very experienced with programming, I’d appreciate any suggestions or solutions that don’t require advanced coding skills.Additionally, I have a similar requirement for another survey where respondents need to answer the same question every 15 minutes. I want to ensure that they adhere to this timing.Any ideas or guidance on how to implement these features would be greatly appreciated.Thank you all in advance for your help!Best regards,
Lorenzo
