I'm trading in my iMac and the disk utility will not let me erase the hard drive. Did i forget to do something?

You have to start in the Recovery Partition (hold down Command + R on startup) and use disk Utilty there.
Try bringing it up and deleting your account as a user. That's what I did with my 2009, 24", iMac.
To add; when you delete yourself as a user, it takes off your data.
Thank you it was a mounting problem. Resolved. Thanks for the suggestions.
You're welcome!
