Qualtrics - How to use the Qualtrics Piped Text Feature Correctly?

Hi Qualtrics community,
Need an assistance please. I'm new to using Qualtrics. The Qualtrics Piped Text is not working on my free account. The description at https://www.qualtrics.com/support/survey-platform/managing-your-account/trial-accounts/ did state that Piped Text works on free accounts. So, basically I would like to display the answer choice selected from Q4 to a question at Q6. But the piped text at Q4 does not want to appear at Q6. I have already selected "Selected Choices" from Q4 as the Piped Text at Q6 question. Refer to the 3 screenshots in this ticket request.
Please advise. Thank you.
