Help with controlling audio

Question

I have a horizontal slider which has left and right buttons to control the movement. I want to have audio narration on each of the clicks so for example. The user is on slide 1, clicks the right button to slide 2 and the audio narration for slide 2 starts, then user clicks the left button to go back to slide 1 and the audio narration for that slide starts etc etc. I currently have a total of 5 slides.
So far this is the code I have:
document.compositionReady:
sym.setVariable("audioplay", "0"); // sets the initial value
Right_btn.click:
sym.getComposition().getStage().getSymbol("SceneHolderSymbol").play();
var audioplay= sym.getVariable("audioplay");
    if (audioplay) {
        sym.setVariable("audioplay", "1");
        // insert your code that you want to do when it's clicked
            sym.$("AF_Slide_21")[0].pause();
            sym.$("AF_Slide_22")[0].play();
else if (audioplay) {
        sym.setVariable("audioplay", "2");
        // insert your code that you want to do when it's clicked
            sym.$("AF_Slide_22")[0].pause();
            sym.$("AF_Slide_23")[0].play();
else if (audioplay) {
        sym.setVariable("audioplay", "3");
        // insert your code that you want to do when it's clicked
            sym.$("AF_Slide_23")[0].pause();
            sym.$("AF_Slide_24")[0].play();
    else if (audioplay) {
        sym.setVariable("audioplay", "4");
        // insert your code that you want to do when it's clicked
            sym.$("AF_Slide_24")[0].pause();
            sym.$("AF_Slide_25")[0].play();
PlayBtn.click: - This is the inital play button which plays the audio for the first page.
sym.$("PlayBtn").hide();
sym.$("AF_Slide_21")[0].play();
I don't know if my approach is completely wrong but any help would be much appreciated.
Thanks,
Phil

Answer 1

Yes, as hemanth mentioned, all of your conditionals are testing for the same condition - is the audioplay variable defined. In your code, that would always be true.
Instead, I think you want to test what the value of audioplay is for each conditional, and then do the appropriate thing.
