Which boolean expression must I include to evaluate?

I believe I have correctly converted the if else statement into a ternary if statement, however I am marked as incorrect with the message

"Bummer: Did you include the boolean expression to evaluate?"

I am unsure of which boolean expression should be included, and no such expression is mention in the question.

CodeChallenge.cs 
int value = -1;
string textColor = null;

textColor = "red" ? value < 0 : textColor= "green";

There are a few issues with the syntax:

  • there should only be one assignment operator (=) on the line (before the ternary)
  • the ternary should have the comparison first (before the ?)
  • after the ?, there should be two values (not complete statements) separated by a colon (:)

You should pass easily once you've fixed these.
