Array's

My prompt is to set the third value in the array to lap3. Whenever I check this all it asks is "Did you index into the third value". I want to say yes?

I'm mostly lost because all of the errors that I receive are yes or no questions that I can answer yes to. Because of this I really don't know where to find the problem. A prior error was that I hadn't set lap3 to a double, so I added a line in there for that. I've been playing around with the lines for a few minutes now and I always get the same errors that don't give me any indicators as to where the real issue is occurring.

CodeChallenge.cs 
double[] lapTimes = new double[4];
lapTimes[0] = 2.2;

double[] finalLapTimes = new double []{2.2, 2.3, 2.5, 2.8};
double lap3 = lap3;
finalLapTimes[2] = lap3;

It looks like you performed the instruction backwards.

You "set the third value in the array to lap3.", but the actual task 4 challenge instruction says "Set lap3 to the value in the third item of the finalLapTimes array."

So if you reverse the assignment operands you should pass.

Also, I don't think it's legal to declare a variable and assign it to itself in the same statement. But you can declare and assign it with something else, that's a standard initialization.

I can't believe I misread that over and over for a thousand times and still never put that together. Thanks you Steven.
