PERL: Creating a Script that Process the Data

New to PERL so I'm suppose to create a script that processes the data (name and number of hours worked during the month) submitted using an online form.The script calculates the number of weeks, days, and hours worked during the month, then displays the form data and the results of the calculations.

I keep getting this compilation error -

Here's my code:
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
$query = new CGI;

# Variables
my $name; #Employee's name
my $hours; #Hours Worked per month
my $weeks;
my $days;
my $hour;
my $remainder;

#Read the user's form input
$name = $query->param('name');
$hours = $query->param('hrs');

$hours /40 = $weeks;
$remainder = ($hours % 40);
($remainder / 8) = $days;
($remainder / 5) = $hour;

#HTML response to user
print "Content-type:text/htmlrnrn";
print "<HTML><BODY>n";
print "Hello, $name.n";
print "You have entered a total of $hours work hours.n";
print "For this month, you have worked $weeks week/s, $days days, and $hour hours.n";
print "</BODY></HTML>n";
