In order to learn Perl, I've started fiddling around with text files. I have a file called-

 siteperf.txt

, Which contains this data-

 A,5000,20
 B,4500,15
 C,4000,10

[download]

All, I want to do is total the values in the second column.

So far I've come up with this-

 $sitePerf = 'siteperf.txt';
 $tot = 0;
 open(F, "$sitePerf") || die ("Could not open $sitePerf!");
 while (<F>)
 {
  ($siteID, $siteAge, $siteDistance) = (split/,/)[0,1];
  $tot = $hash{$siteID} += $siteAge;
  print $tot;
 }
 close (F);

[download]

, Instead of added the data in the second column ($siteAge) together, the script justs concatenates the values and prints-

 500045004000

Your expertise is appreciated,. I've got lots of Perl books out and have been diligently trawling the internet and this is very frustrating!

Thanks
