Which key/value pair is incorrect?

I do not know what is wrong with this code and it keeps telling me to check my spelling but I do not see any discrepancies.

-Thank You for your help

variable_assignment.mm 
NSArray *shoeOrder = @[@"Charles Smith",@"9.5",@"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: 
        @"[shoeOrder objectAtIndex:0]",@"customer",
        @"[shoeOrder objectAtIndex:1]",@"size",
        @"[shoeOrder objectAtIndex:2]",@"style",
        @"[shoeOrder objectAtIndex:3]",@"color",nil];

David Lacedonia This would be the correct answer mate!

NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:
                                      [shoeOrder objectAtIndex:0], @"customer",
                                      [shoeOrder objectAtIndex:1], @"size",
                                      [shoeOrder objectAtIndex:2], @"style",
                                      [shoeOrder objectAtIndex:3], @"color",
                                      nil];

Maybe should be something like this... 

NSArray *shoeOrder = @[@"Charles Smith",@"9.5",@"loafer",@"brown"];
NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: 
        [shoeOrder objectAtIndex:0],@"customer",
        [shoeOrder objectAtIndex:1],@"size",
        [shoeOrder objectAtIndex:2],@"style",
        [shoeOrder objectAtIndex:3],@"color",nil];
