automated normalizaion to 1NF

Hi
Please have a look at automated normalization to 1NF, It's not complete though. just wanted to know if I'm going right. If somethings seems wrong, please let me know. I have to do some error handling and all. 
code refactoring/making translatable is also need to be done.  
Also, I feel the messages written by me is not very clear in various steps, need some suggestions to make them clear to users.
Hi Smita,
I understand your point, but I agree to shorten the message as suggested by Isaac. We have to assume that the user followed the procedure correctly. But this gave me an idea: there could be a small paragraph somewhere (probably at the start of the dialog, available as a hint) that tells the user to carefully follow the procedure in order to obtain correct normalization.
