//dynamic Text field called “track” to capture true or false values
//dynamic text field called “feedback” lets user know if answer is correct or wrong
//button called “submitBTN” if track.text=true then when you press submitBTN it does //something

// It all works except; I want user to click all 3 correct answers before they can click
submit.

//right now if you click on correct answer you can click submit.

//Can anyone help me.

/*
on(release) {
if(track.text == “true”) {
gotoAndStop(“correct”);

if(this.question1_true.onPress = true ) {
question1_true._alpha = 15;
feedback.text = “Great Job!”;
track.text=“true”;

}
}

question2_false.onRelease = function () {
if(this.question2_false.onPress = true ) {
question2_false._alpha = 100;
feedback.text = “Sorry, that is incorrect”;
track.text=“false”;
}
