Lua custom amulet wont work

[ziggy46802]

Okay, I have it set right in movements.xml and in items.xml because it used to work but was bugged, and ever since I fixed it I can't get it to work again. Here is the script

	function onEquip(cid, item, slot)

		if (getPlayerVocation(cid) == 8 or 4) then
			local sword = getPlayerSkillLevel(cid, 2) 
			local axe = getPlayerSkillLevel(cid, 3)
			local club = getPlayerSkillLevel(cid, 1)
			local base = getCreatureMaxHealth(cid)

	if sword => 40 or  then
		setCreatureMaxHealth(cid, (base + sword))
			if (getCreatureMaxHealth(cid) = base - sword) then
				doCreatureAddHealth(cid, sword)
		return true
		end
	return true
	end


	if axe => 40 then
		setCreatureMaxHealth(cid, (base + axe))
			if (getCreatureMaxHealth(cid) = base - axe) then
				doCreatureAddHealth(cid, axe)
			return true
			end
		return true
	end

	if club => 40 then
		setCreatureMaxHealth(cid, (base + club))
		if (getCreatureMaxHealth(cid) = base - club) then
			doCreatureAddHealth(cid, club)
		return true
		end
	return true
	end
return true
end
else
doCreatureSay(cid, "You can not wear this amulet as you are not a knight.", TALKTYPE_ORANGE_1)
return true
end

function onDeEquip(cid, item, slot)
	setCreatureMaxHealth(cid, base)

return true
end

When you put the amulet on, it just does not change your hp at all, even as a knight and with axe as 81
