There are 2 key conceptual problems here.

Firstly you reference @files in a location where it has not been declared. You need to consider scoping with regard to subs.

Secondly, you have put your new code inside a for loop which is itself inside a while loop. Can you explain why you think this means it would only be executed once?

Thank you for your answer. To be clear, I want this statement: `print "Enter the desired number of columns: ";` to be printed just once in the begining of the program for all the files inside the folder, right now it asks for every file.	[reply] [d/l]
