Okay this is the error i get when i try to load my script

Sneed-Boss.LUA:40: 'end' expected (to closed 'function' at line 6)

heres my lua

function Sneed_Shredder_Volley(Unit, Event)
   Unit:CastSpell(37161)
   Unit:CastSpell(30007)
end

function Sneed_Shredder_Spawn(Unit, Event)
   Unit:RemoveEvents()
if Unit:GetHealthPct() < 2 then
   Unit:SpawnCreature(64002,Unit:GetX(),Unit:GetY(),Unit:GetZ(),7,0)
end

function Sneed_Shredder_Cleave(Unit, Event)
   Unit:FullCastSpellOnTarget(30014, Unit:GetRandomPlayer(0))
end
   
function Sneed_Shredder_Disarm(Unit, Event)
   Unit:CastSpell(30013)
end

function Sneed_Shredder_onCombat(Unit, Event)
   Unit:RegisterEvent("Sneed_Shredder_Cleave",10000,0)
   Unit:RegisterEvent("Sneed_Shredder_Volley",35000,0)
   Unit:RegisterEvent("Sneed_Shredder_Disarm",20000,0)
   Unit:RegisterEvent("Sneed_Shredder_Spawn",1000,0)
   Unit:SendChatMessage(12,0,"We shall not be defeated!")
   Unit:CastSpell(29982)
  end

function Sneed_Shredder_onLeaveCombat(Unit, Event)
   Unit:RemoveEvents()
end

function Sneed_Shredder_onDeath(Unit, Event)
   Unit:SendChatMessage(12,0,"Gah! No not my machine")
   Unit:RemoveEvents()
end

RegisterUnitEvent(64001, 1, "Sneed_Shredder_onCombat")
RegisterUnitEvent(64001, 2, "Sneed_Shredder_onLeaveCombat")
RegisterUnitEvent(64001, 4, "Sneed_Shredder_onDeath")

And help would be create

[Aznex]

 function Sneed_Shredder_Volley(Unit, Event)
   Unit:CastSpell(37161)
   Unit:CastSpell(30007)
end

function Sneed_Shredder_Spawn(Unit, Event)
   Unit:RemoveEvents()
if Unit:GetHealthPct() < 2 then
   Unit:SpawnCreature(64002,Unit:GetX(),Unit:GetY(),Unit:GetZ(),7,0)
end

function Sneed_Shredder_Cleave(Unit, Event)
   Unit:FullCastSpellOnTarget(30014, Unit:GetRandomPlayer(0))
end
   
function Sneed_Shredder_Disarm(Unit, Event)
   Unit:CastSpell(30013)
end

function Sneed_Shredder_onCombat(Unit, Event)
   Unit:RegisterEvent("Sneed_Shredder_Cleave",10000,0)
   Unit:RegisterEvent("Sneed_Shredder_Volley",35000,0)
   Unit:RegisterEvent("Sneed_Shredder_Disarm",20000,0)
   Unit:RegisterEvent("Sneed_Shredder_Spawn",1000,0)
   Unit:SendChatMessage(12,0,"We shall not be defeated!")
   Unit:CastSpell(29982)
  end

function Sneed_Shredder_onLeaveCombat(Unit, Event)
   Unit:RemoveEvents()
end

function Sneed_Shredder_onDeath(Unit, Event)
   Unit:SendChatMessage(12,0,"Gah! No not my machine")
   Unit:RemoveEvents()
end
end

RegisterUnitEvent(64001, 1, "Sneed_Shredder_onCombat")
RegisterUnitEvent(64001, 2, "Sneed_Shredder_onLeaveCombat")
RegisterUnitEvent(64001, 4, "Sneed_Shredder_onDeath")

function Sneed_Shredder_Spawn(Unit, Event)
   Unit:RemoveEvents()
if Unit:GetHealthPct() < 2 then
   Unit:SpawnCreature(64002,Unit:GetX(),Unit:GetY(),Unit:GetZ(),7,0)
end

the function requires one "end" and the if statement requires another
so i added one at the end
