the relevant code is 
while (<filehandle>) {
   if (/do_add/) {
      [some stuff here]
   }
}

It does not execute the code inside the if... but if I change the regexp to /add/ instead... code inside the if is executed, but on a bunch of lines in addition to the do_add line from the input file. (add appears throughout the file)
