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)
