Hey, Lilly! I'm so sorry I missed your message yesterday- I was not in a position to look at links when I hopped into the forum. I am trying to decipher your link.

When you're in your book item- what is the number right under your name? That's what you use for an {item:######} entry. The book entry number {entry:#######} is located when you open that specific entry in the book (looks like 6) and you'll see it with the title on one end of the entry and a six or seven digit number on the right side corner.

The links will look like this: "Don't Tell Your Mother"  [13+] for the book itself and "Don't Tell Your Mother - Synopsis" .
