Ken:
Note to self, don't go writing to support boards when I am already half

are, just I couldn't think of the name when I was writing my original post.
And in my instance variable programming, I forgot that you have to run this
no matter if it is an instance variable or not:
globalVariable = [[NSMutableArray alloc] init];
