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.
