How do you assign an owner to a tycoon and call upon them in script?

So I've just got into scripting and I am trying to make my first tycoon. I'm not sure how to assign the owner of the tycoon to a variable and call upon it when they make purchases. I have the leaderboard running, however whenever I try to put the "Owner" variable in place of my name it says that "Owner" is not a player. I've been looking for a solution for a few hours but I can't seem to find it. If I could find a fix to this it would solve all of my problems.

Here's the code I'm using now

local owner = game.workspace.tycoon.StartingScript
local function steppedOn2(part)
	
	local player = part.Parent
	if game.Players:GetPlayerFromCharacter(player) then
		local player = game.getPlayerFromName(owner)
		if game.Players.owner.leaderstats.Cash.Value >= 50 then
		game.Players.owner.leaderstats.Cash.Value = game.Players.owner.leaderstats.Cash.Value - 50
		Cannon.Parent = game.Workspace.Tycoon
		CannonPad:Destroy()
	end
end
end

CannonPad.Touched:connect(steppedOn2)

Thanks for the help

###The script won’t know if you’re the owner. You’ll have to do something like this:

local plrs = game:GetService"Players"

local function steppedOn2(part)
    local plr = plrs:GetPlayerFromCharacter(part.Parent)
    
    if plr then
        if plr.UserId == game.CreatorId then 
            -- your code here
        end
    end
end

###DataModel.CreatorId holds a read-only int64 number. This is the UserId of the owner.
