Introduction

This is a short script that implements a tombola system to pay a randomly picked agent an certain amount of money.

Setup

In order to set this system up, you need to create a notecard called 'Winners containing key and agent ID pairs. An example notecard could contain the following items: 

1ad33407-a792-476d-a5e3-06007c0802bf#Morgan LeFay
f0d95467-3e63-4dfe-bc1e-7b163c6e1006#Trend Clowes

Next, you need to create a primitive and drop the notecard in that primitive. You also need to set the primitive's description to the amount of money that will be paid to a randomly picked agent from that notecard.

Copy the script below and change the access list to contain the names of the agents that will be allowed to use the tombola system. The names have to be the user-names of the agents and not the display names.
