Perhaps I didn't explain well enough.
The tiledbackground needs to start out invisible and become visible with the associated text object "Inv".
When you click the bag/letter looking sprite a bunch of text is created and the tiledbackground is toggled to visible.
The problem is that Inv text is beneath tiledbackground. In this capx that background is on a completely different layer below and it still creates text underneath tiled. You can enable the toggle inventory grouping to see the color changes of Inv text.
