Could anyone tell me what is wrong with this code? please.

within the variable assignment this code challenge is proposed but even thou I think the code is correct it does not accept it as correct answer.

NSMutableDictionary*carDict;
  carDict = [NSMutableDictionary alloc] ; 
[carDict initWithObjectsAndKeys: @"Make", @"Honda", @"Model", @"Accord", nil];

Two things. First, it said explicitly it wanted it done in one statement. Second, you have the keys and values backwards:

NSMutableDictionary *carDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Honda", @"Make", @"Accord", @"Model", nil];
