@chrisdkemper Just reading your recently released book due to research work for my master thesis. Although the Gist link was missing (maybe not the final version of your ebook on Springer?), I fortunately managed to find it.

There's a small typo included:

MATCH (product4:Product {uuid: "d8d1b958-1542-11e5-b60b-1697f925ec7b"),(product5:Product {uuid: "d8d1bade-1542-11e5-b60b-1697f925ec7b"}) --> MATCH (product4:Product {uuid: "d8d1b958-1542-11e5-b60b-1697f925ec7b"}),(product5:Product {uuid: "d8d1bade-1542-11e5-b60b-1697f925ec7b"}) (curly brace missing within first product)

Keep up the good work!

Edit: I found this to be a working Gist with v2.2.8 of Neo4j.

@mbusch Thank you very much for your update, I've now put the correction in the main gist.

Also, the microsite is now online at chrisdkemper.co.uk/beginning-neo4j so any other updates that are brought to my attention will be referenced on there, or I'll update the original gist as I have here.

Thanks again for the correction! :)
Chris

Thanks mbusch. Your "With Sales1" did the trick for me too!
Without that line, i get an error in the last portion.

• CREATE UNIQUE (sale1:Sale {name: "Sale 1", active: TRUE}) : UNIQUE is not required and it leads an error.
• WITH sale1 is required just before MATCH in line 63.
