4,510 PointsDid you include the boolean expression to evaluate?
I know whats being asked but im not sure of the syntax of how to add it ive tried to few different ways but no luck
int value = -1;
string textColor = null;
(value < 0) : textColor = "red" ? textColor = "green";

So a typical ternary expression in an assignment might look like this:
variable = (test condition) ? (value if true) : (value if false)
Give it another try, I'll bet you can do it now.

4,510 Pointsim still having trouble with the bool expresssion
int value = -1; string textColor = null; bool (value < 0) = true;
(value < 0) ? textColor = "red" : textColor = "green";

229,708 PointsYou still have two assignment statements inside the ternary. There should be only one assignment, and it should use the ternary to obtain the value.
The "variable" in my generic example would be "textColor" in this case.
