I have done something similar in a html table (using CGI)
Here's the part of code, hope it helps:

##########to set date/year code ############
@months = qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec);
@weekDays = qw(Sun Mon Tue Wed Thu Fri Sat Sun);
($second, $minute, $hour, $dayOfMonth, $month, $yearOffset, $dayOfWeek
+, $dayOfYear, $daylightSavings) = localtime();
$year = 1900 + $yearOffset;
my @years = ($year, $year+1,$year+2);
######################################################
########To have the years, and use them###############
my @years = (2006,2007,2008,2009);
my $query = new CGI;
####Other cgi code####
print $query->Tr(
        $query->popup_menu(
        -name => 'syear',
        -values => \@years,
        -default => $eyear,
        -labels => @years,
    )
);

Depending on where you have the problem, you can use the code.
