Hello, Try the following: listie = {{0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 1, 1, 0, 0, 0, 1, 0, 0, 0}, {0, 0, 0, 0, 1, 1, 0, 0, 2, 0}, {1, 0, 1, 0, 0, 1, 0, 1, 0, 0}, {1, 3, 3, 4, 2, 2, 5, 3, 2, 1}, {7, 2, 2, 3, 4, 4, 0, 3, 1, 3}} Map[Length, DeleteCases[listie, 0, 2]] Output = {0, 3, 3, 4, 10, 9} I presume this is what you want? (I am a bit confused by your other post). Anyway .... Hope this is of use Tom Dowling.
