The logs are telling:

 in 'string', line 74, column 2:
     patronus
     ^
could not find expected ':'
 in 'string', line 75, column 9:
       worth: 1500

You are missing a colon after all of the spell names starting with patronus

Also make sure there are at least two spaces before every "worth", it's hard to tell from here if that's wrong if the formatting just got lost when you pasted it.
