how to add rescue email address for existing account.

There are instructions on that page that you posted from :

You can edit or delete your rescue email address using theApple ID website. To edit your rescue email address:

1. Navigate to appleid.apple.com using your web browser.
2. Click "Manage your account"
3. When prompted, sign in using your Apple ID and password.
4. Click Password & Security
5. You'll be asked to answer 2 of your 3 security questions before you can make any modifications. If you are unable to remember your answers, you can choose to send an email to your rescue email to reset your security questions.
6. After you've validated your identity by correctly answering your security questions, click Editto the right of your rescue email address.

As well as being able to edit an existing rescue email address you should be able to add one if you don't currently have one.

it won't let you choose the "reset your security questions" if you don't have a rescue email already, and it wont let you add a rescue email with out answering the security questions.

Yeah I am having the same problem

If you can't remember the answers and you don't have a rescue email address then go to Express Lane and select 'iTunes' from the list of 'products' in the middle of the screen.

Then select 'iTunes Store', and on the next screen select 'Account Management'

Next choose 'iTunes Store Account Security' and fill in that you'd like your security questions/answers reset.

You should get an email reply within, I think, about 24 to 48 hours (and check your Spam folder as well as your Inbox)

What happens if we've forgotten our security questions?

<Email Edited by Host>

Why can't you call Apple, and have you tried the suggestions in the user-tip that I linked to in your own thread : https://discussions.apple.com/docs/DOC-4551 ?

And these are user-to-user forums, another user on here won't be able to get your answers reset for you

I can't call apple i don't have phone just i pad

I send e mail to apple support he say i should call apple support team

I can't really , any one help me please

I can give the serial number of my device and any info.

These are user-to-user forums, nobody on here will be able to get your questions reset on your account apart from yourself. You don't have access to any phone ?

But i cant call , just writing
