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.
Does this hint only apply to the first step, or to add steps? I guess it will apply to all steps, so I would put it near the radio buttons.
