Why cant i print spell info?

[mentalnutsy]

I know I am probably missing something obvious but cant work it out. Below is the code I am working with. The function is being called (highlighted below) but it just keeps returning nill.
(I'm not that good at lua and still learning so please simplify as much as possible thanks.)

NuttyWarAnnounce = LibStub("AceAddon-3.0"):NewAddon("NuttyWarAnnounce", "AceConsole-3.0", "AceEvent-3.0")

function NuttyWarAnnounce:OnInitialize()
    -- Called when the addon is loaded
end

function NuttyWarAnnounce:OnEnable()
self:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED")
end

function NuttyWarAnnounce:COMBAT_LOG_EVENT_UNFILTERED(event, timestamp, subevent, srcGUID, srcName, srcflags, dstGUID, dstname, dstflags, spellID)
	if UnitGUID("player") == srcGUID then
		if subevent == "SPELL_AURA_APPLIED" then
			if NuttyWarAnnounce.spellids.shouts[spellID] then			
				NuttyWarAnnounce:sendmessage()
				else if NuttyWarAnnounce.spellids.alerts[spellID] then
				NuttyWarAnnounce:spellcastcheck()
				end
			end
		end
		
		if subevent == "SPELL_AURA_REMOVED" then
			if NuttyWarAnnounce.spellids.shouts[spellID] then
				NuttyWarAnnounce:sendmessage()
			end 
		end
	end
end

	function NuttyWarAnnounce:spellcastcheck()
	print(spellid) --not working
	end
	
	function NuttyWarAnnounce:sendmessage()
	print ("test")
	end
NuttyWarAnnounce.spellids = {
	shouts= {
				[43308] = "find fish", --used for testing purposes--
