Within Ban Man Pro, you must use:

var pr_redir='[BanManProURLEncoded]%26BanManProRedirect%3D$CTURL$';

Note that PointRoll requires the & and = be encoded which are %26 and %3D respectively.  Please always test the click on the live site and make sure it is working properly.  Clicking on the banners screen may not work, so please test on the live site.

Note: You must be using Ban Man Pro version 9 or higher for the variable [BanManProURLEncoded] to be supported.
