Don't know what I'm doing wrong

Don't know what I'm forgetting

CodeChallenge.cs 
string input = Console.ReadLine();
int temperature = int.Parse(input);

if (temperature < 21) 
{ 
    System.Console.Write("Too cold!"); 
}
else (temperature == 21) 
{ 
    System.Console.Write("Just right."); 
}
else (temperature == 22)
{
    System.Console.Write("Just right.")
}
else if (temperature > 22) 
{ 
    System.Console.Write("Too hot!"); 
}

You mostly forgot the "if" keywords.

In an "if ... else if ... else" chain, only the very last condition can be a plain "else", all the others (after the first) must be "else if".

Also, a plain "else" would not have a conditional expression, since it catches everything that the previous conditions did not.
