I am trying to increase the $count variable by 1 whenever any line in the opened file contains the word Mailto:

However, I kept receiving use of uninitialised value $count error and a long string of numbers at the end as the result.

my @email = <OPENFILE>; close OPENFILE; my $count; foreach my $email (@email){ if ($email =~ /mailto:/) { $count += 1; } print $count; # error here }
