I am doing my best to set up open graph on my website.

It's all working ok and looking good on Facebook, but I'm getting this error message on my site:

Object at URL 'http://www.thesocialnetworkingacademy.com' of type 'website' is invalid because the given value '159229554128788' for property 'fb:admins' could not be parsed as type 'fbid'.

Can anyone tell me in fairly basic terms what I need to do to fix that?
