Updated, fixed a lot of bugs. Still not working. Like I said I have a list of 'bad' file extensions, this script should go through a directory of files (and subdirectories), and zip up (in separate zip files for each bad extension), all files WITH those bad extensions in the directories it finds them.

What is wrong???
