Player is a nil Value?

I'm making a game that has a cash IntValue in it and it says that Players.CreeperAssassin005.Backpack.RustyShovel.Script:13: attempt to index local 'player' (a nil value). Any help?

script.Parent.blade.Touched:connect(function(hit)

if script.Parent.CanDamage.Value == true then

script.Parent.CanDamage.Value = false

hit.Parent.Humanoid:TakeDamage(20)

if hit.Parent.Humanoid.Health == 0 then
local  humanoid = hit.Parent:FindFirstChild("Humanoid")
    if humanoid ~= nil then
	  local player = game.Players:GetPlayerFromCharacter(hit.Parent)
      local money = player.leaderstats.Cash
      money.Value = money.Value + 999999
end
end
end
end)

try this

script.Parent.blade.Touched:connect(function(hit)

if script.Parent.CanDamage.Value == true then

script.Parent.CanDamage.Value = false

hit.Parent.Humanoid:TakeDamage(20)

if hit.Parent.Humanoid.Health == 0 then
local  humanoid = hit.Parent:FindFirstChild("Humanoid")
    if humanoid ~= nil then
if player ~= nil then
      local player = game.Players:GetPlayerFromCharacter(hit.Parent)
      local money = player.leaderstats.Cash
      money.Value = money.Value + 999999
end
end
end
end
end)

script.Parent.blade.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") then
		if script.Parent.CanDamage.Value == true then
	   		  local player = game.Players:GetPlayerFromCharacter(hit.Parent)
 			  local money = player:WaitForChild(“leaderstats”).Cash
				script.Parent.CanDamage.Value = false
				hit.Parent.Humanoid:TakeDamage(20)
    				money.Value = money.Value + 999999
		end
	end
end)

script.Parent.blade.Touched:connect(function(hit)
	if script.Parent.CanDamage.Value == true then
		script.Parent.CanDamage.Value = false
		if hit.Parent:findFirstChild("Humanoid") then hit.Parent.Humanoid:TakeDamage(20) end
		if hit.Parent.Humanoid.Health == 0 then
			local player = game.Players:GetPlayerFromCharacter(hit.Parent)
			if player then
				local money = player.leaderstats.Cash
				money.Value = money.Value + 999999
			end
		end
	end
end)

And if that doesn't work, there is probably something wrong with your tool. Try debugging it before saying it doesn't work. Use print() and warn().
