wasnt sure exactly what you wanted, this will Swap users credits depending on probability. I basically stole the code from Steal item as a quick reference.
so basically, using your example. daniel15 has 1000 credits and you have 200. after using item and its successful, daniel15 has 200 credits and you have 1000
copy and paste the code into Swap.php
