Why doesn't the join line show up in Access 2007?

It’s driving me crazy! I keep re-doing the steps shown in the text book and I even re-do the whole thing but the join line never shows! How am I supposed to join two of these two tables? Is there a button I can just press? I don’t get it.
If someone wants to e-mail me at michelle21689@hotmail.com that is willing to help, I can send you a file for you to check if you wish.

Thanks!
