Hello

I am not taking this challenge but let think about the logic out of curiosity

if(temperature <21)
{
    Console.WriteLine("Too Cold!");
}
else if(temperature <=22)
{
    Console.WriteLine("Just right");
}

the second block is only applicable when temperature == 22. Otherwise, the first block is the first to catch the parameter.

Have you tried == instead of <= and see if you get same error?

:point_right: An else statement does not take a conditional expression.

But you can make it into a comment to make the functionality clear:

else  // (temperature >22)

Also, you might be missing some punctuation in your string "Just right" — It should have a period at the end.
