Why does Remote Function not seem to change value?

I recently made this script, it's basically a core for changing stats from local scripts. The game is Filtering Enabled. When invoked, it'll send over the value it wants to change and what the value is. But whenever valuename is "Health", "Strength", "Speed", "Kagune", "Quinque" it says it's a nil value, the error occured at line 10 i think. Even though there is a value in playerdata. It only seems to work when the valuename is "Playing"

local replicatedstorage = game.ReplicatedStorage
local remoteinstance = replicatedstorage:WaitForChild("RemoteInstance")
local gamedata = replicatedstorage:WaitForChild("GameData")
local remote = remoteinstance:WaitForChild("ChangeStat")

--Variables

function remote.OnServerInvoke(player, valuename, value)
	local playerdata = player:WaitForChild("BaseValue")
	if valuename == "Health" or "Strength" or "Speed" or "Kagune" or "Quinque" then
		if playerdata:FindFirstChild("SkillPoint").Value > 0 then
			if gamedata:WaitForChild(valuename).Value > playerdata:WaitForChild(valuename).Value then
		playerdata:FindFirstChild("SkillPoint").Value = playerdata:FindFirstChild("SkillPoint").Value - 1
		playerdata:FindFirstChild(valuename).Value = playerdata:FindFirstChild(valuename).Value + 1		
			else
print("Max Stats!")						
			end
		end	
	end
	
	if valuename == "Playing" then
		playerdata:WaitForChild(valuename).Value = value
	else
		
		playerdata:WaitForChild(valuename).Value = value
end
	end
