I've changed the if/else statement to a ternary if statement. The format looks just like it does in the lesson but it's still giving me an error and asking if I included the boolean expression to evaluate. I thought that the boolean expression was whether "value" is less than 0.
Can anyone point me to what I'm doing wrong here?
int value = -1;
string textColor = null;
public bool ColorChoice(int value)
{
return (value < 0) ? textColor = "red" : textColor = "green";
}

And 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;

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