Hello, I am a student learning Perl and I have a question regarding redirection. My script works fine with the exception of the redirection. If I leave one field blank it shows the link of the page I want to display. If I leave two fields blank it shows two links to the page I want to display etc. Can anyone tell me what I am doing wrong? The book I am using is CGI/Perl by Diane Zak. This book doesn't explain things clearly. Any help would be appreciated. Attached is my script... 
#!c:\phpdev\perl\bin\perl.exe
print "Content-type: text/html\n\n";
use CGI qw(:standard -debug);

#prevent Perl from creating undeclared variables
use strict;

#declare variables
my ($Salesperson, $Sales, $Size, $Rate, $Percentage, @records, @errors
+, $errors, $bonus);


#assign input items to variables
$Salesperson = param('Salesperson');
$Sales = param('Sales');
$Rate = param('Rate');
$Percentage = param('Percentage');

#determine size of @errors array
$Size = @errors;

#calculate bonus rates
$bonus = $Rate * $Sales;
  if ($Salesperson eq "") {
     print "Location:
     http://localhost/cgi-bin/c12ex3b.html\n\n";
}

if ($Sales == "") {
      print "Location:
     http://localhost/cgi-bin/c12ex3b.html\n\n";
}

if ($Rate == "") {
      print "Location:
     http://localhost/cgi-bin/c12ex3b.html\n\n";
}

else {
print "<HTML>\n";
print "<HEAD><TITLE>Patton Industries</TITLE><BASEFONT SIZE=5></HEAD>\
+n";
print "<H1>Bonus Calculation</H1>\n";
print "<BODY>\n";
print "Salesperson: $Salesperson<BR>\n";
printf "Your bonus is: \$%.2f<BR><BR>\n", $bonus;
printf "You entered a sales amount of \$%.2f and a \n", $Sales;
printf "bonus rate of %.1f%%.<BR>\n", $Rate * 100;
print "</BODY>\n";
print "</HTML>\n";
print "</BODY></HTML>\n";
}
