Hi,

For most cases, the parameter "Page name" corresponds to the page name in the URL. If the URL looks like "facebook.com/page-name", its page-name.

There are some cases where the URL looks like "facebook.com/pages/page-name/a-long-number" (it's the case for Charlotte Wessels's page), entering page-name won't work: you have to enter a-long-number instead.

So for Charlotte Wessel, entering 156346401053951 should work. For Delain (facebook.com/delainmusic), it's delainmusic.
