Unfortunately, when I copied the code in as plain text there were two outcomes. The first is that people can cut and paste. The second was that the apostrophes weren’t purely ASCII apostrophes because Wordpress converted them to specialized characters.

While you could replace the extended character set apostrophes in an editor and run the sample code, it was tedious. Your error appears to indicate that the quotes aren’t matched.

I’ve updated all the code to now work with a direct copy into your console or file. It’s one of the reasons why I moved the blog off wordpress.com because they don’t provide that control for plugins.
