Aspiring devloper has problems with a script. Any ideas?

inside a p:art called "Spirit" there are two scripts:

one Supposedly should give EXP when touched by the "WaterEssence":

P.D.: "EXP" is in a folder named "leaderstats" inside the character

local ATM = script.Parent

ATM.Touched:connect(function(entity)
	
	 print(entity:GetFullName())

    if entity.Parent.Name == "WaterEssence" then

 
        local Man =  entity.Parent.Parent.Parent
        local RealMan = game.Players:GetPlayerFromCharacter(Man)
        local Bro = RealMan.FindFirstChild("leaderstats")
        local EXP = RealMan.Bro:FindFirstChild("EXP") 
         EXP.Value = EXP.Value + 100
         print(EXP.Value)
         wait(1)                  
     end
 end)

the other one just makes it invisible.

script.Parent.Touched:Connect(function(hit)
    if hit.Parent.Name == "WaterEssence" then
	script.Parent.Transparency = 0.5
	wait(20)
	script.Parent.Transparency = 0
  end
end)

the invisible script works fine, but the other one shows this error:

error: Workspace.Spirit.Script:12: attempt to index local 'RealMan' (a nil value)

if you dont have any ideas, please give me an alternative way to do it.

Thanks to everyone, SuVee, Aspiring Dev
