point problems

I'm trying to make it so when a players unit devours a neutral unit the neutral units point value is registered to that player on the leaderboard. Any ideas on how to go about doing this? I tried the following but it doesn't seem to be working.

Events
Unit- A unit owned by (Owner of (Triggering unit)) Is issued an order targeting an object
Conditions
(Issued order) Equal to (Order(Devour)
Actions
Set Points[(Player number of (Owner of (Triggering unit)))] = ((Point-value of (Targeted unit)) + (Points[(Player number of (Owner of (Triggering unit)))] + 0))
