How to change MaxHealth?

I keep getting this error

Workspace.ServerScript:98: attempt to index nil with 'MaxHealth'

the error is coming from this function

function ImplimentData(Player, Humanoid)
	for RankName, RankTable in pairs(DataModule.Rank) do 
		if Update == false then
			if RankTable.Name == Player.Data.Rank.Value then 
				Humanoid.MaxHealth = RankTable.MaxHealth -- this is line 98
			end
		else
			if RankTable.Name == Player.Data.Rank.Value then 
				if Player.Data.Exp.Value >= RankTable.ExpLimit then 
					local Difference = Player.Data.Exp.Value - RankTable.ExpLimit
					UpdateRankData(Player, RankTable.NextRank)
					Player.Data.Exp.Value = Difference
					UpdateExpData(Player, Player.Data.Exp.Value)
				end
			end
		end
		Update = false
	end
end

I identified Humanoid in lines 201 - 209

Players.PlayerAdded:Connect(function(Player) -- lines 201
	DataCreate(Player)
	GetData(Player)
	Player.CharacterAdded:Connect(function(Character)
		repeat wait() until Character:FindFirstChild("Humanoid")
		local Humanoid = Character.Humanoid
		ImplimentData(Player, Humanoid)
	end)
end)  -- lines 209

DataModule is a ScriptModule in ServerStorage I named it DataModule in ServerStorage but the table name is DataProperties. This is the code

local DataProperties = {
	Rank = {
		F = {
			Name = "F",
			MaxHealth = 150,
			ExpLimit = 1000,
			NextRank = "E"
		};
		E = {
			Name = "E",
			MaxHealth = 200,
			ExpLimit = 2000,
			NextRank = "D"
		};
		D = {
			Name = "D",
			MaxHealth = 250,
			ExpLimit = 3000,
			NextRank = "C"
		};
		C = {
			Name = "C",
			MaxHealth = 300,
			ExpLimit = 4000,
			NextRank = "B"
		};
		B = {
			Name = "B",
			MaxHealth = 400,
			ExpLimit = 5000,
			NextRank = "A"
		};
		A = {
			Name = "A",
			MaxHealth = 500,
			ExpLimit = 100000000000,
		};
	
	};

}

return DataProperties;

Can anyone help me with the error is it because of placement, because i already tried changing the position of the function in the script i still retrieved the same error. Thanks for review my script, your help is appreciated.
