Lua Particle Effect Won't Spawn

[Sheeplie]

I'm trying to spawn a cool looking Vortigaunt orb at the player's location. However, it's not happening.

I'm simply doing this:

[B]Edit: Wait, it is there- just really small and hard to notice if you're not in a pitch black room. I'll work on it.[/B]

game.AddParticles( "particles/vortigaunt_fx.pcf" )
PrecacheParticleSystem( "vortigaunt_charge_token_d" )

-- Later on in the file..

ParticleEffectAttach( "vortigaunt_charge_token_d", PATTACH_ABSORIGIN_FOLLOW, ply, 0 )
print( "Particle spawned." )

Help is, as always, appreciated.
