I keep running into the same problem on Unreal engine; I add a question to my Q&A game but for some reason it doesn't work. The question does not show up and it just skips to the scorecard

This is a screenshot of my Blueprint and as you can see there is 7 questions but when I run the game i ended up only getting 6 questions

When you check your current question against the last index of your question list, for question 7 both the last index and the question will be 6 so it will fail the > check, arrays are 0 based so the first index will be 0 and the last 6. Normally I would check if the question was less than the size of the question array, that way when you are on the last question it would be a 6 < 7 check and it would pass.
