Reflection does not reflect

Hi,

I’ve wrote a form where users have to put their data in at the beginning and later see, what they have put in.

I wanted to use the reflection tool for it, but it does not work. I even tried the code from the example:

Your country
    

[checkbox* your-country use_label_element “China” “India” “San Marino”]

[reflection your-country “(nothing selected)”]

<label> Choose number [range* your-range min:10 max:99] </label> You chose [output your-range "0"]

But even this code does not work in my contact form. Do I have to add other settings or information?
