Alice,
I reread your post and think I understand now what you are trying to
do. Every time the while() loop runs (for each line in $fh2) the
$total_time variable gets set to '0'. When the if/else loop runs 0 gets
added to $lines and the result will always be the value of $lines.
If you want the $total_time to increment with each line in the $fh2
file then you need to declare it outside the while() loop instead of
inside the loop.
Cheers,
James
