The most common cause of a syntax error I see in the classroom is a missing semi-colon on the line before the one reported.
By the way, do your tests against $input work? Hint: it's good to
chomp.
Also:
if($input =~ /[^1-9]/){ # Used to check for input words.
...
}
if($input =~ /[1-9]/){
print "\n";
}
Is probably better written as:
if($input =~ /[^1-9]/){ # Used to check for input words.
...
}
else {
print "\n";
}
You don't really want to do more regular expression matches than you have to.
