Using BodyMedia armband with MFP-Help Please :-)

NJL13500

I just got my BodyMedia armband in the mail yesterday and wore it today. I love it, but I'm really confused with how to merge it with MFP. I like using MFP to enter my food and just want to let the BodyMedia calculate my calories burned over the course of the day. With this scenario, how do I set my MFP calorie goal so it matches my BodyMedia? I linked the two accounts, but MFP shows me as having more calories left than BodyMedia. I currently have my MFP set to my BMR and the BodyMedia added in my activity for the day.

Can anyone who uses the armband help a girl out?

Thanks!
