$sumof needs to be outside of the while loop otherwise it will keep getting reset to zero and you should be using strict and warnings or even better in my opinion a v string (v5.14). Use local variables.. that is my $x; my @z;

hope this helps, - Rudolf 

use v5.14;

my @allfiles = <C:/Users/user/Desktop/DOwork/filez/nabillingscript/09_
+14_2012/nas/*>;

 
for my $file (@allfiles)
{
     open (FILE ,'<', $file) or die $!;
     
     my $sumof = 0;                         
     while(<FILE>){
           my $lines = $_;
           my @kbused = split(/\s+/,$lines);
           push(my @kilo, $kbused[2]);                             

           for my $aline (@kilo){
                $aline =~ s/\D//g; 
                push (my @onlynums, $aline);  
                $sumof += $_ for @onlynums;
           }
      }
      print "$sumof\n";
}
close FILE;
