Advanced/Complex Fill In The Blanks needs a file
Found Advanced Fill In the Blanks which fits my needs. Apparently it's now Complex Fill in the Blanks, not supported by Core. (Why not? it's great!)
Made a nice little content bit for my demo site, but on uploading to Content Bank in Moodle, I'm getting the error:
Missing main library H5P.AdvancedBlanks 1.2
Checked to see if this was on github but no joy.
Any clues, suggestions, or pointers please?
