UBB.Developers Forums UBB.classic V6 MultiHack Mods [6.0x] Anchor Hack 6.04 Final [ Finished ]

I installed the hack and im getting a error on line 482 in ubb_new_reply.cgi.

here is the code that is around that line.

#Anchor Hack 7
if (($stat_line[2] + 1) > $vars_display{HTMLDisplayMax}) {
$doextra = int(($stat_line[2])/$vars_display{HTMLDisplayMax}) + 1; <------ This is line 482
$doextra = "&p=$doextra";
}
my $anchor = $post_number;

Any idea what may be causing this?
