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,

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!
print "That was it!\n";
last;
} else {
print "Too large. Try agian!\n";
}
