Why won't this password work?

Recently I entered Andre Rodriguez's password on my Wii. I checked it twice, found some mistake, changed them and then I pressed ok, but it did not make *bing!* kind of sound it made the sound you get when you're in success mode when your stats, motivation, coach/scout appeal has decreased, etc... That's the sound it makes. But I still had everything right! Anyone have any ideas or comments about this?

First, it has to be for the same year and console.

Second, it may have changed.

Third, no matter how many times you look it over, it's nearly impossible to be 100% sure it's right.
