Discogs (pone mod) no longer works

Bear with me, I barely know what I'm doing. I added juvalu's .src file (finally figured out it goes in the sources folder) and made yorickausyps edits (to line 124 and removing the space after the colon). I now no longer get an error message. I get the same result as yorickausyps (track numers with no names). How do I get the track names? And more importantly, I used to get composer information because I edited the Discogs Pone 4 Web Script Settings.mp3 file and added the following to the ARTIST NAMES field

Extrafields: >COMPOSER:Written-By<
>COMPOSER:Written By<
>COMPOSER:Composed BY<
>COMPOSER:Songwriter<

I followed these instructions: Discogs, Composed by or written by info?

But I don't get track names or composer information. Thanks for any help.
