hello all, this is my first post here and I have searched for answers elsewhere before asking for help. My code is pretty tight, but I keep coming up with symbol not found errors. Are my curlys not in the right place? Or have i not declared the objects correctly. I could use a look, because I cannot get it for the life off me. Thank you!

oh wow! thanks! I knew it was something simple that I was over looking. Thank you again!

Hi there.. you only hava two same errors as far as I know.. in line 84 and 111. Array.length() is wrong. length is not a method, so take the braces out. it should just be album.length and label.length... no braces. it should compile after you take the braces out.
