Okay, so I’m probably missing something fairly obvious here, but I can’t for the life of me work out what’s going on. Code below.

then lower…

I’m currently getting these errors:

- UI.ConsoleLogger is not a constructor
- UI.WindowManager is not a constructor
- this.element.down(this.options.container) has no properties

I assume the last is due to the first two errors, but I’m really lost here. I’ve even tried simplifying it further by removing all other HTML/JS from the page, and still get those 3 errors. Anyone? :(
