Which email address are you trying to change ?

You won't be able to change the rescue email address until you can answer your security questions, if you can't remember your answers and gave a fake email address for it then you will have to contact Support in your country to get the questions reset.

Contacting Apple about account security : Contact Apple for help with Apple ID account security

If your country isn't on that page then try this form to contact Support : https://www.apple.com/emea/support/itunes/contact.html
