Need help with Jass Spell Code

scope KatonJutsu initialitzer KatonInit
/////////////////Setup///////////////////////////////////////////
globals
private contstant integer SPELL_ID = 'ANcl'

private function Katon_DMG takes integer Katonlevel returns real
return level *50
endfunction

private function Katon_Range takes integer Katonlevel returns real
return level *150
endfunction

private function unit KatonTargets takes nothing returns boolean
return (GetWidgetLife(KatonTargets) > 0.405) and (IsUnitType(KatonTargets, UNIT_TYPE_STRUCTURE) == false) and (IsUnitType(KatonTargets, UNIT_TYPE_MAGIC_IMMUNE) == false)

/////////////////Globals///////////////////////////////////////////
globals

private group Enemies // if the spell can be used by multiple ppl/characters then I should create a global group, because the spell wouldnt have to create a new group for every Caster then which could create lag)
private boolexpr K    // "This offtipic is for group aswell" also, if CreateGroup is used in automatic functions like the inizializer, it can crash the Game sometimes unless u only set it in the initializer which only works if u created a group beforehand which we did now

/////////////////PickedUnitsInRange///////////////////////////////////////////
private function KatonPick takes nothing returns boolean

return KatonTargets(GetFilterUnit())

private function Katon_Condition takes nothing returns nothing

endfunction
/////////////////Actions///////////////////////////////////////////
private function Katon_Action takes nothing returns nothing

Soo I need help with this Spell I made in vJass. I'm a newbie so go easy on me. I've looked over it for a few times now and re-read severel tutorials, but I can't find my mistakes allthough there are probably quite a few. So I'd be really glad if someone could point out the mistakes I made here so I can improve and do it better next time. PS: Dont mind the // cuz they are meant to remind me of things I thought would be good to know. Anyway thanks in advance

misspelled initializer:

initialitzer

Noticed because Syntax highlighting would give it a different, non-keyword color. Looked weird.
