Hi guys,
Thanks a lot!
You were right - I got multiple lines in the file and
I guess while the variable was set when it found the
correct pattern, but was unset after it couldn't find
the pattern.
Since, I don't need anything after I got my field, I
just used 'last' to exit out from the loop and it
seemed to work fine!
Thanks again!
