Hi everyone!

I am following the Organic Modeling Tutorial 2 and I got to a stage where is suposed to align the midle vertices of the head to the Y axle. Kurt says to select the vertices, go the front view and then move them in Y axle, while pressing 'X' in the keyboard, moving them first to the right side and then moving them back to the Y axle... But when I do this, they continue to be in the same place (unaligned)!

Here is the picture:


Any help is welcome!
