iPhone help - calendar

When I go into my calendar to put in appointments, the little plus sign to add an event is greyed out and I can not create a new event.
Anyone know what I did? How do I fix it?

I would go into your settings and check the Mail, Contacts, Calendars section...I'm not really sure what you did but thought I'd add that piece of advice!

If I was to guess, I'd think somehow your email account(s) were somehow messed up. You might need to reinstall or just verify them.
