Adobe Animate CC HTML5 - Validate multiple buttons & textinput boxes with button

Here's the code ref:

// Multiple button selected with state on, checks & moves on automatically if any 3 buttons are selected:
this.count = 0;
this.totalToGo = 3;

this.check = function(e)
{
if (!e.currentTarget.selected)
{
this.count++;
e.currentTarget.selected= true;
e.target.removeAllEventListeners();
}
if (this.count == this.totalToGo)
this.gotoAndStop(5);
};
this.stop();
this.b1.on("click", this.check, this);
this.b2.on("click", this.check, this);
this.b3.on("click", this.check, this);

this.b4.on("click", this.check, this); // how to define this b4 is a wrong option?

I am also able to check if user has made multiple correct textinputs.

var root = this;

function validateF(){
if($("#answer1").val()=="123" && $("#answer2").val()=="234"){
// correct
root.gotoAndStop("correctProceed");
} else {
// incorrect
root.gotoAndStop("wrongTryAgain");
}
}
this.start.addEventListener("click", validateF);

Need help : To combine these codes to check if the user has clicked multiple buttons correctly & entered multiple textinput boxes correctly. Checking all these only when user clicks a submit button.
