Make sure that your characters are associated with your account, and that your characters are valid to show up there.

If you don't have any characters associated with your account, there'll be nothing to show in the raid availability window.

What's your site's address, and what's your username on that site?

Thanks for your response, Chops. You are correct. The problem was that, on the forums, my character wasn't 80 yet. I changed that manually and now can be seen on the schedule.

Of course, this raises another issue of why my dkp profiler mod isn't working. So, I uninstalled it and reinstalled it and hope that fixes that problem.

Thanks again.

Figured it out. I'm completely good to go. Thanks!
