LUA Script Question

[abndrew82]

I have been reading over some Tutorial on LUA scripting, and think I am learning but for some reason something i had working before I must be doing something wrong with

I have this script

function phase_1(pUnit, Event)
 if pUnit:GetHealthPct() < 90 then
  pUnit:RemoveEvents();
  pUnit:FullCastSpell(16033)
  pUnit:SendChatMessage(11, 0, "Test Oh Shit I am at 90%")
  pUnit:RegisterEvent("phase_2",1000, 0)
 end
end
 
function phase_2(pUnit, Event)
 if pUnit:GetHealthPct() < 60 then
  pUnit:RemoveEvents();
  pUnit:FullCastSpell(33452)
  pUnit:RegisterEvent("phase_3",1000, 0)
 end
end
 
function phase_3(pUnit, Event)
 if pUnit:GetHealthPct() < 60 then
  pUnit:RemoveEvents();
  pUnit:FullCastSpell(34807)
 end
end

function Boss_OnCombat(Unit, event)
Unit:RegisterEvent("phase_1",1000, 0)
end
RegisterUnitEvent(65008, 1, "Boss_OnCombat")

As just a test and the mob seems to cast the spells but isnt saying anything

My other one I am working on that I really want to work is this

function phase_1(pUnit, Event)
 if pUnit:GetHealthPct() < 90 then
  pUnit:RemoveEvents();
  pUnit:SendChatMessage (11, 0, "The Fight has Just Begun!!!"
  pUnit:FullCastSpellOnTarget(38739)
  pUnit:RegisterEvent("phase_2",1000, 0)
 end
end

function phase_2(pUnit, Event)
 if pUnit:GetHealthPct() < 70 then
  pUnit:RemoveEvents();
  pUnit:SendChatMessage (11, 0, "Battle My Minions!!!"
  pUnit:SpawnCreature(65006, -4849, -883, 822, 0.8, 14, 360000)
  pUnit:FullCastSpellOnTarget(30217)
  pUnit:SpawnCreature(65005, -4831, -883, 825, 2.2, 14, 360000)
  pUnit:RegisterEvent("phase_3",1000, 0)
 end
end

function phase_3(pUnit, Event)
 if pUnit:GetHealthPct() < 60 then
	pUnit RemoveEvents();
	pUnit:SpawnCreature(65007, -4849, -883, 822, 0.8, 14, 360000)
	pUnit:SpawnCreature(65007, -4831, -883, 825, 2.2, 14, 360000)
	pUnit:FullCastSpellOnTarget(34697)
	pUnit:SpawnCreature(65007, -4824, -875, 822, 2.8, 14, 360000)
	pUnit:RegisterEvent("phase_4",1000, 0)
 end
end

function phase_4(pUnit, Event)
 if pUnit:GetHealthPct() < 50 then
	pUnit:RemoveEvents();
	pUnit:SpawnCreature(65007, -4824, -875, 822, 2.8, 14, 360000)
	pUnit:FullCastSpellOnTarget(12738)
	pUnit:SpawnCreature(65007, -4831, -883, 825, 2.2, 14, 360000))
	pUnit:RegisterEvent("phase_5",1000, 0)
 end
end

function phase_5(pUnit, Event)
 if pUnit:GetHealthPct() < 25 then
	pUnit:RemoveEvents();
	pUnit:FullCastSpellOnTarget(34036)
 end
end

function Boss_OnCombat(pUnit, event)
	pUnit:RegisterEvent("phase_1",1000, 0)
end
RegisterUnitEvent(ENTRY ID, 1, "Boss_OnCombat")
