Thanks for your post! Someone will need it. And it's a very good sample for customizing a Action element!

I thought somebody could use this; I built it to be able to play random holding prompts.
This is an element that generates a random integer between 0 and some upper bound number (that you provide).
Input an integer and it will return a random integer between 0 and one less than the input.
lets say you need 5 random values:
input 6
