Custom end of survey message

Figured it out!

Can you share how you did it? I'm trying to do the same thing!

I am happy to help share how to do this!
Navigate to your end of survey message, place your cursor wherever you'd like to insert whatever the respondent typed in, and find the piped text icon {A} on the styling options above the text box.
Once you click {A} you will drill down to the question number that you are wanting to use as an insert and select the text entry option. You do not want to select "Question Text" as that will display the question itself, not the response.
Do a quick run through to make sure that this works the way that you expect by using the "preview" button on your survey.
I hope this helps!

Excellent! Thank you so much! It worked :)
