76: Note missing

You started a block with three underscores ___, which mark notes. In your case the underscores are followed by a blank line or by the end of your document instead of the expected note or notes.

Solution

Make sure there is content directly below the underscores. Here is a valid example with footnotes:

___
#1. Brüder Grimm: Schneewittchen
#2. Bechstein: Der kleine Däumling

If you did not mean to create a note but want to use three underscores at the beginning of a paragraph, you can prepend all underscores with backslashes: \_\_\_. If you prepend these partially, the underscores without a leading backslash will be interpreted as marks for supplementary emphasis.
