Anybody know why this isn't working?

it works fine when I use the regular unholy frenzy, but when I plant my custom slk in the map with the custom spell based off it, it doesn't seem to want to carry out the added actions....

function Trig_FastForward_Conditions takes nothing returns boolean
return ( ( GetIssuedOrderIdBJ() == String2OrderIdBJ("unholyfrenzy") ) and ( GetUnitTypeId(GetOrderedUnit()) == 'Hamg' ) )
endfunction


function Trig_FastForward_Actions takes nothing returns nothing
local real mana = GetUnitStateSwap(UNIT_STATE_MANA, GetOrderedUnit())
local unit caster = GetOrderedUnit()
set udg_FFCast = true
loop
exitwhen (( mana > GetUnitStateSwap(UNIT_STATE_MANA, caster)) or (udg_FFCast == false))
call TriggerSleepAction( 0.01 )
endloop
if (udg_FFCast == false) then
return
endif
call CreateNUnitsAtLocFacingLocBJ( 1, 'eC01', Player(0), GetOrderPointLoc(), GetUnitLoc(GetTriggerUnit()) )
set udg_Booster = GetLastCreatedUnit()
endfunction

function InitTrig_FastForwardCode takes nothing returns nothing
set gg_trg_FastForwardCode = CreateTrigger( )
call TriggerRegisterPlayerUnitEventSimple( gg_trg_FastForwardCode, Player(0), EVENT_PLAYER_UNIT_ISSUED_TARGET_ORDER )
call TriggerAddCondition( gg_trg_FastForwardCode, Condition( function Trig_FastForward_Conditions ) )
call TriggerAddAction( gg_trg_FastForwardCode, function Trig_FastForward_Actions )
endfunction
