Help with sentences corrections

Hello there.

I’m a real newbie to actionscripting.

I really need to make this and i dont know how, so im asking you for help.

It goes like this:

Simple questions with 4 possible awnsers, BUT instead of one being correct, two correct awnsers are needed to succeed and only after these two have been clicked, it will appear the “next” button to go forward.

I know how to make everything to have it displaying wrong or correct when you click each of them, but i really dont know how to make it needed to have 2 clicked awnsers to proceed, or that since i click on one of them, flash knows that it is already clicked and only one lasts to pass.

Anyone can give me some hints?

Im sending a simple fla file for you to see if it’s correct or if i need to change alot of stuff. Its in portuguese, but dont worry, the words are just rabbish to try the functioning.

thanks all.

need something like this:

onEnterFrame = function(){
if(textField1.text == "answer1" && textField2.text == "answer2"){
nextButton._visible = true;
}else{
nextButton._visible = false;
}
}
