Luis,

This looks like just a minor syntax problem. After "initwithObjectsAndKeys," pass the "shoeOrder" array.

It should look like this: 

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

If you have any additional questions, feel free to ask!
