I'm making a leveling system and dont know how to use the module with it, help?

i made a leveling system recently and i want to make it so it changes the needed exp according to the module SERVER SCRIPT

Exp.Changed:connect(function()
        fightingdata:SetAsync(player.UserId, value.Value)
        leveldata:SetAsync(player.UserId, level.Value)
        expdata:SetAsync(player.UserId, Exp.Value)
        neededdata:SetAsync(player.UserId, NeededExp.Value)
        if Exp.Value > NeededExp.Value then
            wait(0.5)
            local expleftover = Exp.Value - NeededExp.Value
            NeededExp.Value =  "" -- what the module says for the next level
            Exp.Value = expleftover
            level.Value = level.Value + 1
        end
    end)
