Halo itkamaraj

I try to run this code (ami.pl)
Code:
$ perl -e 'my $total=0; while (<>) { chomp; my $value = (split /([,:])/)[2]; $total=$value+$total; }print $total/$.' fps.csv

but still can't work. I place my fps.csv and ami.pl in one folder at my dekstop. Once I click ami.pl it will just pop out and nothing happened in fps.csv. I try to add break; at the end of the code but still the .pl file close automtically.
