Hi

I'm trying to design a dating website for a school assignment given a synthetic data set. I was trying to display 10 profiles per page with links to the next and previous page. I've tried a whole heap of things but it always seem to get some sort of error on the href lines. I was hoping someone could point out where i went wrong. Also, Perl seems to complain that i have unmatched curly braces when i had the right number of braces. Removing the ending brace for the while loop and the subroutine seemed to have fixed that but now i'm actually missing two braces! Here's my subroutine: 

sub browse_ten {
        my $page = 1; # intialise number of pages
        my @users = glob("users_dir/*);
        #entire array of all the user files to be displayed.
        my $pages_required= ceil(($#users)/10); #calculate how many pa
+ges to display
        while ($page le $pages_required) {
                my $start = ($page - 1) * 10; # index to begin display
+ing them
                my $end   = $start + 10; # show 10 results per page
                $end = scalar(@users) if $end > scalar(@users); # cap 
+the end

                # whether to show links
                if ($start > 0) {
                        # Show a Previous link
                        print "<a href=\"engcupid.cgi?page=" + ($page 
+- 1) + "\">Previous</a>";
                }
                if (scalar(@users) > $end) {
                        # There's more entries after what's being show
+n
                        print "<a href=>\"engcupid.cgi?page=" + ($page
+ + 1) + "\">Next</a>";
                }

                # Show the range of entries.
                for (my $i = $start; $i < $end; $i++) {
                        my $user_to_show = $users[$i];
                        $profile_filename = "$user_to_show/profile";
                        open $p, "$profile_filename" or die "cannot op
+en $profile_filename: $!\n";
                        if(-r "$user_to_show/image.jpg"){
                                print img({src=>"$user_to_show/image.j
+pg", width =>150, height=>$150});
                        } else {
                                print img({src=>"blank_profile.jpg", w
+idth=>150, height=>150});
                        }
                        $profile = join '<br>', <$p>;
$profile .= "<br>";
                close $p;
                print $profile;
                }
                $page = $page+1;
