Hi! Thanks for the video, it was the only that worked for me. Just a question, How could I calculate the average of each line if all the values to calculate are in the same line? And, then, How can I append this average to the end of each line? For example: 1, 2, 3, 4 3, 4, 1, 4 => 1, 2, 3, 4, 2.5 => 3, 4, 1, 4, 3 Thanks in advance.
