not getting calorie burned upload from fitbit

You have to have the base plugged in for it to sync what's on your fitbit with the fitbit website. Then I find it takes between 1 and 5 minutes most of the time for fitbit to update MFP. (I've seen it take as long as 30 minutes too!)

You press and hold the button until a timer comes on for sleep mode. Then wear it on your wrist at night. When you wake up, press and hold the button until the timer stops.

Do you have your fitbit on the dock? Sometimes that's how I just upload the data depending on how long I have, I sometimes don't have five minutes to wait around for it to wirelessly upload. Also, the way I understand it, how fitbit works with mfp, you log your cardio on mfp but also pay attention to the time and log the correct starting time. That way the fitbit doesn't double count your cardio during that time. Also, some days you'll see a calorie adjustment on mfp from fitbit, some days you won't depending upon the day (how much cardio you did, calories, etc) I log all my meals on mfp and they transfer to the fitbit site also, not as individual foods but as "meals" from mfp. I hope this helps!
