I'm making a tycoon, but I encounter this output "error" on this line. How do I fix this?

Before, I also had a error with a script that used "Head" but I had two bricks named "Head". I'm using Zednov's Tycoon Kit (or** Zed's Tycoon Kit**) and I encountered this output "error" (not sure if orange is error) that I will put here: Infinite yield possible on 'Workspace.Zednov's Tycoon Kit.Tycoons.Fighting Bears.PurchasedObjects:WaitForChild("Wall2")' It comes after it runs this script:

if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then

There are also multiple "errors" like the one I have put down. I'm asking this because I want to make a tycoon, but when you buy the first dropper, you can't progress. Could someone please help me?

EDIT :: So the first "Error" issue is fixed, thanks Astreal. But I still need to fix my tycoon. I can make a model of it, if that helps.

That's not an error, it's actually a warning. It's simply letting you know that it currently pausing until it finds an object named 'Wall2.' To fix this, you can actually just put a part inside of the object 'PurchasedObjects' and call that part 'Wall2.' That will fix this issue. Hope I helped! :)
