I'm pretty sure that I'm following all of the coding correctly, but every time I change something it gives me an internal error. Please help. Here is my config:

Pretend that the spaces are all there I know that those are correct because I just copy and paste.

Please wrap all item info (enchantments) in 'single quotes' (like that).

E.g.
'0': '261 51:1 48:1'
