i need help getting to setup my rescue email

The steps half-way down the page that you are posting from should work. If not then what happens ?

If you are posting because you've forgotten the answers to your security questions then you will need to get them reset first - you won't be able to add one until you can answer 2 of your questions. In which case see if this user tip helps : https://discussions.apple.com/docs/DOC-4551

e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then try Apple ID Account Security

or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
