I am supposed to make this simple program. It produces a multiplication problem, and when the user types the correct answer, it is supposed to produce another question. Instead it goes into an infinite loop and never stops, the answer field and the button go away. Also, I am supposed to make the comment about the users answer, one of 4 different sayings. Without using Arrays how would I do that?
My professor is no help, really getting aggravated as I have no where else to turn.
<html>
<title>HW 9.27 and 9.28</title>
<head>
<script type="text/javascript">
var number1;
var number2;
var answer3;
var answer2;
function problem() {
number1 = Math.floor(1 + Math.random() * 9);
number2 = Math.floor(1 + Math.random() * 9);
document.writeln("How much is " + number1 + " times " + number2 + " ?");
answer2 = (number1 * number2);
}
function answer1() {
var statusDiv = document.getElementById("status");
answer3 = document.getElementById("answer").value;
if (answer3 != answer2) statusDiv.innerHTML = "No. Please try again";
else if (answer3 == answer2) {
statusDiv.innerHTML = "Very good!";
problem();
}
}
problem();
</script>

<input id="answer" type="text" />
<input type="button" value="Solve!" onclick="answer1()" />
<div id ="status">Click the Solve button to Solve the problem</div>
