Over my head..

Ternary if statement just flew over my head.. coding the tower game is starting to get challenging. I kinda understand what needs to be done but at the same time I'm lost. like what is the ?-operator again? Can someone please walk me through.

CodeChallenge.cs 
int value = -1;
string textColor = null;
{
return (value < 0) textColor = "red" ? textColor = "green";
}

The ternary should be used as a single expression, use "if" for statement control. Try placing the variable on the left side of the assignment, and the complete ternary on the right.

Also, you can't use "return" here, it's just for inside functions and methods.

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