Custom particle effects can't be found?

I made a bunch of custom particle effects and they’re in the particle folder in my ep2 folder but what should I type into the name area of my particle_system entity? Lets say my .pcf file is called “customfire” and my particle system is called “newfire”. I tried the name of the system and it said it couldn’t be found ( newfire ). Then I tried the name of the pcf then the system name ( customfire
ewfire ) but still no luck. I’m sure i’m making a stupid mistake but I’m at a loss here. Anyone know what to do? Thanks!

You type the name newfire, and add the pcf to the particle_manifest.txt

Thanks!
