All expression used to require you to input the input letter though this was causing troubles when people changed the components to full names options so David changed it so all component expressions now take x as the input instead.

Also if you watching older tutorials watch out for Item index and Shift path, the Wrap option on these used to be set as false by default (would not loop number to start/end of list, this has since been changed to True by default.
