SMS code validation screen

Learn how to create a prototype using SMS code validation. First, we'll use a hidden input field to capture the actual text input, then simplify the process with using the left() and right() formulas instead of complicated focus in / focus out logic to move from one field to the next. We'll also use a detect on hidden input field so that when the 6th digit is entered, the code is validated, and either moves on to the next scene or shows an error if the incorrect code is entered.
