Adding to my list

It seems that I'm having trouble to add new movies to my existing list
Can anyone help

Ok just figured it out

Can you or anyone else help me with this? I noticed recently the 'add to collection' button has been removed from the bottom of the search results pages. How exactly do I go about adding new DVD's to my 'Owned' list? Any help is much appreciated.

Where it says 'Mark as' is the search results, you just have to click on owned.
