what Nathan had done was a constructive comment on how it could be redone with a much simpler code and tidier looking. he has identified various errors and explained what they are and how to correct them. i too have been on the recieving end from many of my scripts from where i have submitted a warts'n'all type of coding which whilst it worked for me was able to have been vastly improved on. it is these comments that we should use to help us code better for the future hopefully
