[JASS] Jass bulleting system. Nothing happened

I activated the function with this triggger:

function Trig_Unbezeichneter_Ausl__ser_001_Action takes nothing returns nothing
    call Bullet('BU01',gg_unit_XWIN_0007,5,GetUnitFacing(gg_unit_XWIN_0007),1000,50,1,0,0,0,0,0,0,0,0)
endfunction

//===========================================================================
function InitTrig_gf takes nothing returns nothing
    set gg_trg_gf = CreateTrigger(  )
    call TriggerRegisterPlayerChatEvent( gg_trg_gf, Player(0), "-go", true )
    call TriggerAddAction( gg_trg_gf, function Trig_Unbezeichneter_Ausl__ser_001_Action )
endfunction

But there have only been a Gryphon Rider(BU01) spawned...Why?
