Trigger not running

[Blazing_Legion]

The following trigger Isn't running and I can't figure out why. hoping someone can provide some insight.
Useful(Maybe) Information:

-BLOOD_RAIDER, STOMP, BERSERK, etc are constant global integers set in the trigger above it at init and represent numbers 0 -22
-The trigger is not initially on but does get enabled when it needs to be (Checked with DebugMsg)
-TOTAL_CAST_GROUPS is set to 23

What I've tried:

-replacing constants with their number equivalents
-replacing call TriggerRegisterTimerEventPeriodic( gg_trg_CastAbilities, 1/(TOTAL_CAST_GROUPS / 2) ) with call TriggerRegisterTimerEventPeriodic( gg_trg_CastAbilities, 0.032 )
-Debug msgs to check that the group im trying to test actually has units in it

Unfortunately, let alone cast the abilities none of the messages in the trigger even show up.

Thanks for any Help.
