(Tycoon upgrades) Can someone help me with this Problem(adding another dropper)?{FIXED}

As the error says, there isn't something called "Object" inside a model. The model in question is v on line 41, which is a child of script.Parent.Buttons. That means one of the models there must not have an object called Object.

This code is really complicated looking. There's no reason to write code that is indented 11 levels deep. Simplify.

Here's a whole host of improvements to your code:

• Use math.random() instead of math.random(1, 255) / 255.
• Don't need to say ~= nil in a condition. It's easier to read just if player then, etc.
• Similarly, no need to say == true.
• Don't use coroutine.resume(coroutine.create(. Just use spawn(.
• Use good variable names. v is a button. You don't use i so you should call it _.
• Don't define an anonymous function that's 9 levels of indentation deep inside of 2 levels of indentation. Make a named function for it.
• :WaitForChild can't return nil, so it doesn't make sense to use it an if.
• Try writing a function for the fading, rather that duplicating that code twice.
• Try using and instead of just embedding ifs in each other.
• You try to get a player from a part touching fairly often. Why not right a function?
• Consider using an early return in case of failure (not player or not button.Head.CanCollide) to reduce indentation levels

In the end, I've gotten something like this, which is at least a little cleaner:

---handles all buttons

objects = {}  ---empty erray for script
teamcolor = BrickColor.new(script.Parent.Name)
config = script.Parent.Parent.Parent.Configuration
wait(1)

script.Parent.Essentials.Spawn.TeamColor = teamcolor
script.Parent.Essentials.Spawn.BrickColor = teamcolor

function syncFade(part, time)
	for i = 1, 20 do
		part.Transparency = part.Transparency + 0.05
		wait(time / 20)
	end
end

script.Parent.Essentials.Collector.Touched:connect(function(hit)
	if hit:FindFirstChild("Cash") then
		script.Parent.Cash.Value = script.Parent.Cash.Value + hit.Cash.Value  --checks if they ahve cash and takes the price from it
		Instance.new("Sparkles",hit).Color = Color3.new( math.random(), math.random() , math.random() )
		game.Debris:AddItem(hit,0.1)
	end
end)

function getPlayer(part)
	local character = part.Parent
	if character then
		local player = game.Players:GetPlayerFromCharacter(character)
		local humanoid = character:FindFirstChild("Humanoid")
		if humanoid and humanoid.Health > 0 then
			return player
		end
	end
end

script.Parent.Essentials.Giver.Touched:connect(function(hit)
	local player = getPlayer(hit)
	if player then
		if script.Parent.Owner.Value == player then  ---makes sure that it is the owner
			---makes sure thta the player is alive when touched
			local cashmoney = game.ServerStorage.MoneyStorage:FindFirstChild(player.Name)---checks the storage for cash
			if cashmoney then 
				cashmoney.Value = cashmoney.Value + script.Parent.Cash.Value
				script.Parent.Cash.Value = 0  ----makes sure that they have enough money to buy the item
			end
		end
	end
end)

function buttonTouched(button, hit)
	local player = getPlayer(hit)
	if not button.Head.CanCollide or not player then
		return
	end
	if script.Parent.Owner.Value == player then
		local cashmoney = game.ServerStorage.MoneyStorage:FindFirstChild(player.Name)
		if cashmoney then
			if cashmoney.Value >= button.Price.Value then
				cashmoney.Value = cashmoney.Value - button.Price.Value  ---makes sure you have enough money
				objects[button.Object.Value].Parent = script.Parent.PurchasedObjects ---makes the object go away until bought
				if config.ButtonExplodeOnBuy.Value then
					local explosion = Instance.new("Explosion",workspace)
					explosion.Position = button.Head.Position
					explosion.DestroyJointRadiusPercent = 0
					explosion.BlastPressure = 0
				end
				if config.ButtonFadeOutOnBuy.Value then
					button.Head.CanCollide = false
					spawn(function()
						syncFade(button.Head, config.ButtonFadeOutTime.Value)
					end)
				else
					button.Head.CanCollide = false
					button.Head.Transparency = 1
				end
			end
		end
	end
end

script.Parent:WaitForChild("Buttons")   ---- waits for all the buttons to arrive
for _, button in pairs(script.Parent.Buttons:GetChildren()) do   
	if button:FindFirstChild("Head") then   ---makes sure it is a button
		local object = script.Parent.Purchases:FindFirstChild(button.Object.Value)---look for an object by the name of the button
		if object then
			objects[object.Name] = object:Clone()  --- clones the object
			object:Destroy()  ----destroys the object
		else
			print("Button: " .. button.Name .. " is missing its object and has been removed.")
			button.Head.CanCollide = false
			button.Head.Transparency = 1   ---removes the button
		end
		if button:FindFirstChild("Dependency") then
			button.Head.CanCollide = false
			button.Head.Transparency = 1
			spawn(function()
				script.Parent.PurchasedObjects:WaitForChild(button.Dependency.Value)
				if config.ButtonFadeInDependency.Value then
					syncFade( button.Head, config.ButtonFadeInTime.Value)
				end
				button.Head.CanCollide = true
				button.Head.Transparency = 0
			end)
		end
		button.Head.Touched:connect(function(hit)
			buttonTouched(button, hit)
		end)
	end
end

Though I think you could probably simplify even more.
