alloc and init challenge is Where is my mistake ?

NSString *myRide = [[ NSString alloc] init]; *myRide = [[carDict valueForKey:(@"Make")]

I don't know where is my mistake :(

variable_assignment.mm 
   NSDictionary *carDict = [[ NSDictionary alloc] initWithObjectsAndKeys:@"Honda",@"Make",@"Accord",@"Model", nil ];

NSString *myRide = [[NSString alloc] init] ;
        *myRide  [ carDict valueForKey: @"Make"]

Really close:

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

NSString *myRide = [[NSString alloc] init] ;
myRide  = [ carDict valueForKey: @"Make"]; //no * when using variable, and you need an = sign, to assign value to myRide
