Help editting a money printer by adding a variable

[TypeCode713]

What I'm trying to do is combine the money printer extra code for a money collector to making the printer itself collect the money without spawning the money itself. Whatever I try it just doesn't seem to work.
It's fairly choppy at the moment, I plan on cleaning it up later, but I need it working first.
Problem I am having is the display works, money still spawns and drops on the printer.
Please no complete rewrites, just a good nudge in the right direction, I wanna learn how to do this for future reference.

Here's my code: (and by "my", I mean a lot of copy pasted code, credit to their respected authors.)

Can you show us the original code?
