May be I didn't explained my prob exactly.
I don't have a problem with the regex (and yes, I have the /m /g and /s).
Related to the regex, my script works fi

What is your actual regex? At a minimum, you'll need /g modifier. You may
need /m and/or /s as well.
Hello,

You should limit the scope of $lines to the foreach loop. Does $lines
contain multiple lines or just one line? Perhaps you sho

First, it doesn't look like you're using 'strict', which means you're not
declaring your variables. This is probably going to lead to trou

Actually that is an "append". Maybe there is a definition issue, aka I would think of
an "overwrite" to be a ">" where
open the file with ">>"
This will cause an overwrite..

Try removing the newline at the end of your question with a call to chomp.
else{
for (my $i=1; $i<=$#qk+1;$i++){
chomp ($Question_hash{$qk[$i-1]});
print In1

Can someone take a look at this and see what is wrong? I am still

The email.txt file is an empty file and has the correct permissions.
