Hi, everyone. Thanks for your help again last night. If you don't mind,
I have another question. I'm working on another assignment and have
almost everything worked out, but one of my if statements is acting
weird, and I can't figure out why. It's reporting an error when it
shouldn't be. I've gone over my code several times, and everything seems
fine to me. Can someone please take a look? The grades.txt file I
attached is used by my program. Thanks.
