How can I calculate an age?

How can I calculate an age.  I have followed the directions from https://www.jotform.com/answers/1539288-How-to-calculate-the-age-in-form

But it seems a key function is covered by the a red arrow

You need to use the Date Picker tool and the Form Calculation widget in order to achieve this.

Interestingly enough, the other thread is incorrect, the thread shows a
"round" function when it should be "Floor"
