Please help me understand what I need to change in the beggining:
#!/usr/bin/perl -w

my $max_number='';        #initialize a variable that keeps the maximu
+m number
my $current_number='';      #variable that will keep the number of eac
+h line for comparison

while (defined ($current_number=<STDIN>))
{
    chomp ($current_number);                        
    if($current_number > $max_number)                
    {
        $max_number = $current_number;            #compare each time t
+he number we have in the line with the max number    
    }
}

print "The maximum number of all in your file is: ".$max_number."\n";

The error I get is: 
Argument "" isn't numeric in numeric gt (>) at myscript.pl line 9, <ST
+DIN> line 1.

The program works, but I think I did not set my $max_number=''; correctly... What should I put there?
