Getting SKSE's GetMagnitude() function to work

[BuggerBurger]

I seem to have trouble with SKSE's GetMagnitude() function ( http://www.creationkit.com/GetMagnitude_-_ActiveMagicEffect ) to work with my spells. self.GetMagnitude() and GetMagnitude() always returns 0.00000

 

Heres an incredibly basic example script that I'm working with

 

 

 
Scriptname ArexonEnchDragonsouls extends activemagiceffect  
 
Event OnEffectStart(Actor akCaster, Actor akTarget)
 
Float Damage = GetMagnitude() * akCaster.GetAV("DragonSouls")
 
debug.Notification(self.GetMagnitude())
 
akTarget.DamageAV("Health",Damage)
 
endEvent
