The Electoral Commission website has provided 2 helpful pages about the voting process for the new Police and Crime Commissioner on 15 November. http://www.aboutmyvote.co.uk/pcc.aspx and http://www.aboutmyvote.co.uk/how_do_i_vote/voting_systems/police_and_crime_commissioner.aspx
It's especially useful to watch the video they have provided, which explains you can vote for two candidates - a first choice and a second choice, so that's one X in each of the two columns on the ballot paper.

Once elected, the Police and Crime Commissioner will serve until May 2016, a term of 3½ years.
The Electoral Commission has produced a booklet about the election of the Police & Crime Commissioners, a copy of which should be delivered to every household before the 2nd November.
