You've named this thread - your question - simply "help". It would be much better to use something like "removing duplicate lines".

And well, I see you've finally used the board search finding duplicates in columns and removing lines .

Let's put it together:
i) you've used a meaningless topic
ii) you've posted your problem three times
iii) you've already found a thread in which you problem is answered and explained

Do you really believe this will motivate me to explain this to you? I don't.
