Confused Plus and Minus

Today when I checked my wii fit weight, I found that I have failed to reach my goal so I decided to increace the difficulty by putting in that I wanted to add more caleries to my goal but, I confused plus for minus.  When the game told me that I had made the mistake I did not set the goal for my fit meter.  I tried to change it to the right one by going to the bathroom and retaking the test but, there was no change in my goal.  Somehow my goal is to gain 3 pounds.    I blame myself for staying up too late and making that mistake.
