MFP won't sync steps to Fitbit

Hi.. I am very new to MFP.. I have synced my MFP to Fitbit but the steps are still showing 0.
I have followed these steps
- Log into your Fitbit Dashboard and unlink your MyFitnessPal connection from the Fitbit side of things. Log into your Fitbit account, click the gear icon and choose “settings”. Once inside the settings, click the Applications tab and locate MyFitnessPal. Once you find MyFitnessPal click “revoke” access.
- Log into MyFitnessPal and make sure that Fitbit is completely disconnected from the MyFitnessPal side of things. You can see if Fitbit is still linked through our website by clicking Apps, and then seeing if Fitbit is listed under the “Your Apps” section along the right sidebar.
- While still logged into your MyFitnessPal account please reauthorize your Fitbit account.

And still it does not work!! What am I doing wrong???
