Where does the nil termination go?

I'm trying to put it where the preview is telling me, every time I do it states that two errors have be generated. Also this is getting more funny. so thank you all for the help

NSArray *shoeOrder= @[@"Charles Smith", @(9.5), @"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict=[[NSMutableDictionary alloc]initWithObjectsAndKeys:shoeOrder ];

[[NSMutableDictionary alloc] initWithObjectsAndKeys: [shoeOrder objectAtIndex: 0], @"customer", nil];

nil should be at the end. you also have to provide the values and keys. follow the instructions in the code challenge and user this code as a guide.
