When you name a variable, it’s only visible to you when you create the form. When the person fills out your form, they won’t see the variable name. If you recall the variable in your form, they will see the value you’ve inputted for the variable but not the variable name.
I’ve attached two screenshots. The first is of when creating the form, you see the variable name color_quiz on the end screen. The second screenshot is of what the respondent sees, the score they received from the quiz that uses the the color_quiz variable but they won’t see the variable name color_quiz.
one is called “url parameters” and as the name say, its some parameters to pass via the URL, it’s something you already know about your respondent. It could be their name, email, user id, …
Then we have the “variables” in the form, which are used inside the form to calculate things or hold values. Their value is only related to the logic you apply to them.
In both cases you can show them or hide them from the respondent in the body of your form. Just type @ and you should see a box with all the questions and variables available.
Once added you should see this teal box as on @Phoebe VA screenshot
