Does your file have any blank lines?

You know the weirdest thing is...I sat here and stared at this program, and tried to do different things. I finally made a new txt file and now it works perfectly. I don't know why it wouldn't read the other file, but now it's working. I'm gonna see if I can improve the rest of the code.
Thanks so much for your help.
