Attempt to Index nil with..?

So I am trying to make a Leveling System. To gain EXP, you must touch a block. The script is within the Part that needs to be touched. Now, I am getting an error that says ' attempt to index nil with 'LevelsInfo'' The problem is, the script isn't able to find the LevelsInfo which is a Fold with String Values within the Player. I know that I will more than likely have to use a Local Script for this, but why won't it work with a Local Script. If it is possible though to use a normal Script, how would I go about doing that. This is the line that it gets into trouble at 'player.LevelsInfo.Experience.Value += expToGain' Thanks in the long run! -XRangerGuyX

local part = script.Parent
local debounce = false``

part.Touched:Connect(function(hit)

    local player = game.Players:GetPlayerFromCharacter(hit.Parent)

    if not debounce then
        debounce = true

        local playersFinished = 0

        wait(3)
        if playersFinished == 0 then

            print("A Player Has Finished!")

            local expToGain = 3

            playersFinished += 1

            player.LevelsInfo.Experience.Value += expToGain

        elseif playersFinished >= 2 then
            print("A 2nd Player Has Finished!")

            local expToGain = 1

            player.LevelsInfo.Experience.Value += expToGain
        end
        wait(1)
        debounce = false
    end 
end)
