Disappearing Tile Script

With my script I am trying to have the color_changing_tiles_device disappear upon being touched by a player, but I am trying to handle this with many more tiles acting independently from one another. Upon testing in-game, nothing happens when touching a tile except for “Failed” being printed.
I have been trying to figure this out on my own for a day or two, but I can’t seem to figure it out. If someone experienced in Verse could help me out, that would be greatly appreciated!
