as3 can't assign text to a variable

[ryanp321]

Hi, i've gotten pretty close on this one,
i wanted to make a little quiz kind of game, 4 choices and a sum randomly displayed.
And i wanted to assign each time a random choice (to contain the answer)
and i've done that, and can trace that
'rightChoiceBox' = _choice(random num)
and i can trace the answer itself
but what i've commented at the end won't work
I get the error

Scene 1, Layer 'Layer 1', Frame 5, Line 22 1119: Access of possibly undefined property text through a reference with static type String

var answer:String = new String();
answer = String(((sum1)+(sum2)));
var answerString:String = new String();
answerString = answer;

var selectRightChoiceBox:String = new String();
selectRightChoiceBox = String(Math.floor(Math.random()*4)+1);

var rightChoiceBox:String = new String();
rightChoiceBox =("_choice"+ selectRightChoiceBox);

trace(rightChoiceBox);
trace(answerString);

//rightChoiceBox.text = answerString;

That's because you declared rightChoiceBox as a String. The .text property you tried to access belongs to a TextField. Just do

rightChoiceBox = answerString;

Ah, thanks! I understand that now!
A small problem, is there anyway to make a random number, not repeat another 'choices' number?

if(rightChoiceBox == "_choice1"){
	_choice1.text = answerString;
}

if(rightChoiceBox != "_choice1"){
	_choice1.text = String(Math.floor(Math.random()*4)+1);
}

if(rightChoiceBox == "_choice2"){
	_choice2.text = answerString;
}

if(rightChoiceBox != "_choice2"){
	_choice2.text = String(Math.floor(Math.random()*4)+1);
}

if(rightChoiceBox == "_choice3"){
	_choice3.text = answerString;
}

if(rightChoiceBox != "_choice3"){
	_choice3.text = String(Math.floor(Math.random()*4)+1);
}

if(rightChoiceBox == "_choice4"){
	_choice4.text = answerString;
}

if(rightChoiceBox != "_choice4"){
	_choice4.text = String(Math.floor(Math.random()*4)+1);
}

would something like this possibly work?

while(choice4.text == _choice1 or _choice2 or _choice3){
	_choice4.text = String(Math.floor(Math.random()*4)+1);
}

Sorry for asking different questions in the thread
