How do you delete you chao Data in Sonic Adventure 2 battle

Well..
1. Start up the Gamecube
2. Hold down the A button [green] until the cube thing turns around
3. When it goes to the menu, pull the joystck [gray] down
4. You will come up to a memory card manager screen [memory card screen. I just call it manager]
5. Press the A button to enter the manager
6 Look around for a little block with a waving chao in it. I think it is waving, but it should say:
Sonic Adventure 2 Battle
-8- Chao Garden Data
7. Press the A button on the little block that is the same as described as above
8. A small menu will come up:
Copy
Move
Delete
9. Use your gray joystick to scroll up and down the menu
10. Press A on the delete option.
Voila! You just deleted your chao garden data!
