Please help with my battlelog connection to my xbox.

I wanted to connect my xbox's battlefield to the battlelog, but it trys to connect to an email that isnt my xbox lives. (It automatically tryed to connect to my gamertag@live.com) When i go to http://battlelog.battlefield.com I put in my origins account ( which is the same email as my xbox live account) Then it tells me to buy battlefield 3 to access the battlelog... I tryed looking at forums and contacting EA.

If you want pictures for help i can take them.

Can you please help me reddit?
