Tycoon Problem Name is not a vaild members of players?

game.Players is a service, not the LocalPlayer.

You're obviously trying to get the leaderstats of the player that Touched the part. In order to do this, I would suggest using the GetPlayerFromCharacter() function from the players service. First, let's get the character. To do this, simply use part.Parent. To know for sure if the part's parent is the character, check if it has a Humanoid, like so,

function onTouch(hit)
	if hit.Parent:FindFirstChild("Humanoid") then-- Checks for Humanoid
    
	end
end
script.Parent.Touched:connect(onTouch)

Now we can Define the character,

function onTouch(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local char = part.Parent--Define character
	end
end
script.Parent.Touched:connect(onTouch)

Now we get the player by using GetPlayerFromCharacter. Like so,

function onTouch(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local char = part.Parent
		local plr = game.Players:GetPlayerFromCharacter(char)--Get player using character
	end
end
script.Parent.Touched:connect(onTouch)

Now we can throw your code in there!

EDIT, fixed error.

function onTouch(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local char = part.Parent
		local plr = game.Players:GetPlayerFromCharacter(char)
		local check1 = plr:WaitForChild("leaderstats")
		if check1 then
			local check2 = plr:WaitForChild("Owner")
			if check2 then
				local check3 = check2.Value
				if check3 then
					check3 = true
				end
			end
		end
	end
end
script.Parent.Touched:connect(onTouch)

That should work.

However, it seems what you were going for was this,

function onTouch(hit)
    local name = hit.Parent.Name
    if name then
    local check1 = game.Players[name]:WaitForChild("leaderstats")
    if check1 then
    local check2 = game.Players[name]:WaitForChild("Owner")
    if check2 then
    local check3 = check2.Value
    if check3 then
        check3 = true
                end
            end
        end
    end
end
script.Parent.Touched:connect(onTouch)

or

function onTouch(hit)
    local name = hit.Parent.Name
    if name then
    local check1 = game.Players:FindFirstChild(name):WaitForChild("leaderstats")
    if check1 then
    local check2 = game.PlayersFindFirstChild(name):WaitForChild("Owner")
    if check2 then
    local check3 = check2.Value
    if check3 then
        check3 = true
                end
            end
        end
    end
end
script.Parent.Touched:connect(onTouch)

Which would work, but I just provided a slightly better way.

Good Luck!
