Conjured's cash system is a little out of date, but if you're determined to get it working, I believe he included scripts in his pack that gave money to the player (via pickups, I think). Open up those scripts and find out what variable he's using to add money to the player's inventory, then use that bit of the script inside of an enemy's destroy script.

Only those who sow the seeds of their desires will reap their benefits later.
However, I have seeds of my own to tend to. I don't have time to be someone else's watering can.
