"Including boolean value" error

I'm receiving the error:

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

However isn't "(value < 0)" the boolean to evaluate?

int value = -1;
string textColor = null;

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

The entire ternary is an expression.

So it would not normally contain assignment statements, though it's common for it to be used in one.

A typical use of a ternary might have a structure like this:

somevariable = conditional_expression ? value_if_true : value_if_false;

Also, a return statement can only be used inside a function or method.

Very helpful and useful information. I relied too much on the video example for my syntax and structure.
