Maybe simple - but i'm stumped - multiple variables + array

i’m trying to trace this out - but i don’t believe i have the right syntax:

trace (levelNum + “Questions” + [questionNum[currentQuestionNum]].correctAnswer);

i can trace out ‘levelNum’ and it traces out fine. i can trace out ‘questionNum[currentQuestionNum]’ and it traces out fine.

basically without any variables my object array would look like this:

lvl(1 or 2)Questions[(a # here)].correctAnswer.

But my trace is not working and i’m not sure how to group that all together.

thanks.
