Did you include the boolean expression to evaluate? Yes, I did. So now what?

Not sure what I am missing. I am looking at the code in Visual Studio and it seems to work. Any ideas?

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

return (value < 0) ? textColor = "red" : textColor ="green";

Hi there! The problem here is in the interpretation of the instructions. They are asking you to assign the value of "red" or "green" to the variable textColor. The instructions have not asked you to return anything.

The variable you should be assigning to goes on the left of the equals sign as normal. Then the expression to evaluate goes on the right side followed by a question mark. Finally the two values (the first for true and the second for false) go after the question mark and should be separated by a colon.

Here's an example:

myMood = happinessLevel < 0 ? "unhappy": "happy";

In this example if happinessLevel is less than 0, then myMood will be assigned the string "unhappy". Otherwise, it will be assigned the string "happy".

I hope this helps, but let me know if you're still stuck! :sparkles:

You only need to use a return statement if it is in a method. Try this code instead:

I have redacted the explicit answer posted above as an explanation for how/why the code works the way it does was never provided by the original poster of the answer.

Thanks, I have been at this too long. Why was I returning anything. Taking a break.

It takes Practice, and an unbending will.
