Variable in variable in alert not working?

I haven't seen the answer video yet I'm trying to figure out why this doesn't work. If I write out the variable correctMessage (as in Question 2) then correct += 1 works properly and the intended number is displayed. If I try to call the variable correctMessage (as in question 3) then correct +=1 is ignored and only 0 is displayed.

var correct = 0 var correctMessage = "Right! " + correct + " of 5 correct."

// Question 2

var motoAnswer2 = prompt("What motorcycle?") if (motoAnswer2==='gsxr600') {

correct += 1; alert("Right! " + correct + " of 5 correct."); } else {alert(wrongMessage)}

// Question 3

var motoAnswer3 = prompt("color motorcycle?") if (motoAnswer3==='red'){

correct += 1; alert(correctMessage); } else {alert(wrongMessage)}

also, for future reference, how do I display my code when asking for help without copy and pasting here?

I found my answer in the next next video lol. What I wanted is something that wasn't taught yet. instead of having correctMessage as a variable with a variable in it, it needed to be a function.

The "correctMessage" string was created when the program first started, and it used the value of "correct" at that time (which was 0). After that, changing "correct" will not change the string in "correctMessage".

The only solution is to rebuild the string as you did for question 2 to get the current value of "correct" to show.
