Hi, I tried to do this and couldn't get it to work correctly, can you show me what I'm doing wrong? 
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 = $greenbutton;
my @logfile=<LOG>;    # throw logfile into an array
while (<LOG>) {
if ($_ =~ /$error/i) {
  $button = $redbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
     last;
  }
elsif ($_ =~ /$warn/i) {
  $button = $yellowbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
     last;
  }
else {
    print "<!--Content-type: text/html-->\n\n";
    print "$button";
    last;
  }
}
close LOG;
