Weight Ticker isn't updating?

Options
I just joined this site last Sunday and I LOVE IT! I've lost over 130 lbs in the last year and a half and wish to lose another 50-60 more, so when a friend told me about this, I jumped on it. I've changed all of the settings I can find and my Weight Tracker on my page isn't showing the 3 lb. weight-loss that I put in yesterday. Am I doing something wrong?
