OK, here's my latest: 
use strict;
use warnings;
my $logfile="log.txt";
my $error="DOWN";
my $warn="PROBLEM";
my $redbutton="\<img src\=\'default_files/perlredblink\.gif'>";
my $greenbutton="\<img src\=\'default_files/perlgreenblink\.gif'>";
my $yellowbutton="\<img src\=\'default_files/perlyellowblink\.gif'>";
open LOG, $logfile or die "Cannot open $logfile for read :$!";
my $button = $greenbutton;
while ($_ = <LOG>) {
if ($_ =~ /$error/i) {
  $button = $redbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
  }
elsif ($_ =~ /$warn/i) {
  $button = $yellowbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
  }
 else {
    print "<!--Content-type: text/html-->\n\n";
    print "$button";
  }
}
close LOG;

Now, when I test the output upon changing the log values locally, I get exactly the outputs I want; I am using Perl 5.8.8. However, when I test it on my server, which is using Perl 5.6.1 my server-side include to call this file from HTML does some really funky stuff (it actually shows two green, one yellow, two red, one yellow then one red,) but I think that may be a different issue with my server configuration. Should I upgrade the Perl version on my server to get this to execute correctly? Or, are you guys still seeing problems with my code? Thanks for any help.
