What kind of money are you using? Lumber and Gold?
if that was the case, then create n number of array variables with size 12 to accommodate all players, where n is the number of resources that you want to manage.
Then when the player deposits, then just store the number of deposited number in the array variable with the proper index.
Let's say Red Player deposited 500 Gold.
Then do: set SampleArray[PlayerNumberOfRedPlayer] = SampleArray[PlayerNumberOfRedPlayer] + 500
Then decrease the current Player Property Gold of the Red Player.
Or when he takes it out 500 Gold, then:
set SampleArray[PlayerNumberOfRedPlayer] = SampleArray[PlayerNumberOfRedPlayer] - 500
Then increase the current Player Property Gold of the Red Player.
