What have i done wrong with this facebook comment code

[ClaireH-184886]

Hi, i have a page here http://www.in2town.co.uk/trip-advisor/african-safari-is-a-dream-holiday-destination  and i am trying to have a comment section through facebook on there, and although i have got it on, i think i have done something wrong as i can manage or delete the comments.

i have read the instructions but not managing to follow them. i have tried going into the developers section but that just gives me the option of

website

apps on facebook

mobile apps

now i have tried going into these but there is no code or anything, so i am not sure what i am doing wrong.

the way i have done it is, by just using a joomla module as i work in joomla 1.5 but where it says Facebook comments application ID   i have just put my webpage details in there.

the module i am using is
mod_phoca_facebook_comments

any help in finding the application id or the correct way of doing it would be great

thanks
