I finally discovered what the sleep logger is for !

I have been working at this for the 2 months that I have had the Force and have asked many people to help.  Some did but it left me still with my original question (and the Dashboard with the same answer).  So I have concluded that the purpose of the Sleep setting is to print out the sentence: "There is already a sleep during the time period you tried to create the new sleep."  It does not matter what I do;  What state my tracked is in;  What times I enter, how sleepy I am, what the weather is, whether I say "same day" or "different day" etc.  The result is always the same.  It prints: "There is already a sleep during the time period you tried to create the new sleep."

What people have told me in the past was obtained from the para in the manual that says how to log sleep.  But that will not work if all the logger does is say "There is already a sleep during the time period you tried to create the new sleep."  The only setting that stops it from doing that is if I enter a start time that is later than the stop time:  Then it tells me I made an error.  Otherwise it says, "There is already ...." 

If anyone has figured out anything else it does please let me know.

Are you tapping it to start the sleep mode? if so...then you don't have to manually log it. Mine accidently started sleep mode one time about eight hours before going to bed and had about eight hours sleep recorded when I was active and I then turned it off when I went to sleep. Couldn't figure out what time I went to sleep(tapped it to go into sleep mode) that night so just logged manually about 1/2 hour when I figured I went to bed and tapped the fitbit. The log that night was not totally acurate but it gave a log. Hope this helps.

Thanks for responding to my call for help. I put the tracker into
'count' mode making it it run on and on, if that's what you mean by
"tapping". Then I go to the sleep log icon on Dashboard and click
it. Then I get a setup windows with blanks on Start Time and End
Time. I fill then in with the times I will by going to sleep that
night and when I plan to get up, then it says its famous statement
""There is already ...." Do you do anything different?

Okay I have the Flex so right before I fall alseep I tap it about 5 times, right on the light bar. It vibrates and two lights come up (they remind me of eyeballs). I can double check to see if I am in sleep mode by double tapping- the eyes come on. Then when I wake up I tap again rapidly- like 5 or 6 times, it vibrates and all 5 lights come on, then the one light to show I am ready to count my steps. I don't enter anything in my log. The night I forgot to set my Flex I had no sleep recorded so I went into my log and entered the time I fell alseep and when I woke up. It recorded the sleep just fine. It sounds like you are trying to double do it- it says you entered sleep and don't need to again. Is that possible?
