UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Reverse Posting CGI Question

One strange thing, adding lines allows one additional forum to go in reverse, but the final 2 are not affected.
Any ideas?
Syntax is as follows:

#reverse topics?
if ($vars_display{ReverseThreads} eq 'TRUE' || $in{f} == 39) {
@ordered_topic = reverse(@topic_file);
} else {
@ordered_topic = @topic_file;
} # end if/else reverse threads option

#reverse topics?
if ($vars_display{ReverseThreads} eq 'TRUE' || $in{f} == 40) {
@ordered_topic = reverse(@topic_file);
} else {
@ordered_topic = @topic_file;
} # end if/else reverse threads option

#reverse topics?
if ($vars_display{ReverseThreads} eq 'TRUE' || $in{f} == 43) {
@ordered_topic = reverse(@topic_file);
} else {
@ordered_topic = @topic_file;
} # end if/else reverse threads option

#reverse topics?
if ($vars_display{ReverseThreads} eq 'TRUE' || $in{f} == 65) {
@ordered_topic = reverse(@topic_file);
} else {
@ordered_topic = @topic_file;
} # end if/else reverse threads option


The last 2 do not function, the first 2 do.
