explicit package name

Can someone tell me why I am getting the following error?

Global symbol "$quess" requires explicit package name at ./ex10-1.pl line 18.
Execution of ./ex10-1.pl aborted due to compilation errors.

I declare $guess inside the while loop. Shouldn't that suffice for the
rest of the scope?

Thank you,

Chris

#!/usr/bin/perl

use warnings;
use strict;

my $secret = int(1 + rand 100);
# This next line may be uncommented during debugging
print "Don't tell anyone, but the secret number is $secret\n";

while (1) {
print "Please enter a guess from 1 to 100: ";
chomp(my $guess = );
if ($guess =~ /quit|exit|^\s*$/i) {
print "Sorry you gave up. The number was $secret.\n";
last;
} elsif ($guess < $secret) {
print "Too small. Try again!\n";
} elsif ($quess == $secret) {
print "That was it!\n";
last;
} else {
print "Too large. Try agian!\n";
}
}

You declare $guess but the error message says "$quess" (a Q instead of a G).

You have correctly declared the variable $guess, but you are using
$quess here, which doesn't exist. That is the sort of thing 'use strict'
is good at finding for you!

Oh my goodness! Maybe that is a sign it is time to call it a night!

Thanks all! Not sure why I couldn't see that.
