Ok so i've written my first script, it asks for the users name, location etc. 
#!/usr/local/bin/perl
print "\nWhat is your name?";
$username = <STDIN>;
print "\nWhere do you live?";
$userlocation = <STDIN>;
print "\nHow old are you?";
$userage = <STDIN>;
$userage2 = $userage++;
print "\nAre you a boy or a girl?";
$usersex = <STDIN>;
if ($usersex eq "boy") {
$userboy = "he";
}elsif ($usersex eq "girl") {
$userboy = "she";
}
print "$username is $userage2 years old and lives in $userlocation"
." In a year $userboy will be $userage $username is a $usersex";

Problem is $userboy should equal he or she, but it shows up as nothing! how do i fix it?
