How to use the array elements

Hi, i'm trying to automate a questionary using array.

// In the compositionReady for the stage

sym.actual = 0;

sym.arr = [ "Hi","Love","You" ]              // This is my question array.

sym.checkArr = function(){                  // this the function that i use to check whis question of the array i'm going to use.

          sym.Question = arr[actual];      // i want to use the value "Hi", and then increase my "actual" var and then use the value "Love"

}

// In my symbol timeline i use a trigger, in that trigger i use

sym.stop();

sym.quest = sym.getComposition().getStage().Question;         // I'm getting the Question value;

sym.$("Ask").html(quest );                                                         //"Ask" is an empty textfield;

sym.getComposition().getStage().actual ++;                    // Increase "actual" for the nex time.

But the code doesn't work, i think the problem is the way i use the array index.

Please help!

Thanks =)
