I was wondering if you could clear a few things up..

I need different equations depending on what page I'm on, so I devised 

if ($page < 1) {
for ( grep defined($_), ( reverse keys %upload )[ -19 .. 0 ] ) {
}
elsif ($page eq 2) {
my $top = ($page * 20);
my $bottom = $top - 19;

}
else ($page > 2) {
my $top = $page * 20;
my $bottom = $top - 19;
}

On the first if statement, it's printing incorrectly. It's printing images 4, 3, 2, 1, 2 instead of just 4, 3, 2, 1. It must be pulling a range that's to be used with one of the other loops, have any idea how? Because ?page=2 returns images 1, 2, 10, 9... (one of these two aren't supposed to be pulling the 1, 2 but I can't figure out which one).

All pages=3 and up are working properly, it's just page 1 and two which are sharing the same pictures. (When I say picture numbers, it just means I uploaded test images with numbers on them so I could see which order they went in).

I'm using something like that module you said. Any ideas on what part of the equations is wrong?
