When it says:

then add this new function to the file:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// ###################### Start construct_forum_columns #######################
function construct_forum_columns($parentid, $columncount)
{
global $vbulletin, $stylevar, $vbphrase, $show;
global $imodcache, $lastpostarray, $counters, $inforum;

// this function takes the constant MAXFORUMDEPTH as its guide for how
// deep to recurse down forum lists. if MAXFORUMDEPTH is not defined,
// it will assume a depth of 2.

if ($columncount == 0)
{..................

What does it mean, am i just meant to put this at the very end of the file or what?
