Thank you in advance for any help you can give me.

[Henry Wong]

each arrow is pointing at the . in the code the errors are on lines
165

Okay, I will help with the first line... here is the line...

theMusicCDInventory.addMusicCD(theMusicCD);  

At this line, you are calling the AddMusicCD() method. But... Where is the code for this method? You are calling a method that you never defined.
