Error in items.txt

this error is confusing me:
---------------------------
Pokemon Essentials Gen 6

Exception: RuntimeError
Message: Field '' must contain only letters, digits, and
underscores and can't begin with a number.

this is the line as it appears in items.txt, with the lines above and below:

I went and re-copied it and now I have a different error I'm trying to solve.
