4,155 PointsGet one of the answers to be correct in a quiz. So the player gets one more point!
Making a quiz where the user have 3 answer options, I need to make one of the answers correct and the two other false for each object in the array. I'm thinking I need to get the indexNumber of the array and then set one of the key's to true for each object in the array. And then use an if/else function to compare the users answer to the correct answer. Am I on to something there? or Is there another better way?
I'm not sure how to tell the computer that this answers is correct and this answers is wrong. Can I do that in the array?
And since I have 3 options for the player to choose between, I'm thinking that I would connect the button/answer ID to the different keys in the object array, would that work?
Here is my code now

243,199 PointsWhy not add a "correct" value?
In the questions array, for each question, in addition to the three answers you could have another property to indicate which answer is the correct one. You might call this property "correct" and it would contain either 1, 2, or 3.
Then, when an answer button is clicked, you just see if it matches the "correct" value for that question. If so, add the point and give notice of a correct choice, and if not just give notice of an incorrect choice.
