Hi all, after a bit of advice if I could please? I have the following hash that I'm trying to sort by the value against CPU.

$VAR1 = {
          'hostname' => {
                                                    '1' => {
                                                             'pass' =>
+ 1,
                                                             'cpu' => 
+'0.07%',
                                                             'box_name
+' => 'hostname',
                                                             'capacity
+' => '0.41%'
                                                           }
                                                  },
          'hostname' => {
                                                  '1' => {
                                                           'pass' => 1
+,
                                                           'cpu' => '0
+.04%',
                                                           'box_name' 
+=> 'hostname',
                                                           'capacity' 
+=> '0.25%'
                                                         }
                                                },

Here's my code, but I'm getting

Use of uninitialized value in numeric comparison (<=>) at ./cpu_check.pl line 157.

so I must not be doing it properly?

foreach my $router ( sort {$results->{1}{cpu}{$a} <=> $results->{1}{cpu}{$b} } keys %$results )

Thank you
