Hi,
There have been heaps of posts about debugging on this site (how to, why you should, why you SHOULD NOT, what went wrong, how easy it is....the list goes on and on).
Try using the Search facility on this site. Key word: Debugging and you'll see how many people are talking about it!
BTW, I haven't yet, but I have read that debugging only works for Tama Connections (American) or Tama Plus (Japanese), but not for Connexions (European). I don't know for sure if it's true or not....
Good Luck if you do...
Best, etc.
