News and emails - how to add two buttons

Hello I'm begginer,

I would like ask about subscription for customers.

I want create two buttons in store:

[text area]Enter e-mail address[/textarea]

[button]Add to subscription[/button]

[button]Remove from subscription[/button]

Adding and removing must be with activation link which is will sent on e-mail address.

Below is code what i already done in file …\blocks\static_templates\subscription.tpl for addon “news_and_emails”:

```php {** block-description:tmpl_subscription **}

{if $addons.news_and_emails}


{** {include file="buttons/go.tpl" but_name="newsletters.add_subscriber" alt=$lang.go} **}

{/if} ```

Thank you for help and answer
