If/then statement with division

I am trying to write a code that looks at a field and if it equals a specific number (in this case "2"), then it divides another field by that number. Here is what I have so far...

if (this.getField("Tex3").value != 2) {
var numerator = +getField("text1").value;
var denominator = +getField("text2").value;}
// Calculate and set this field value
if (denominator !== 0)
{
event.value = numerator / denominator;
}
else {
event.value = "";
}

It is currently returning nothing.

UPDATED CODE:
if (this.getField("Text3").value == 2)
else {
var numerator = +getField("undefined_10").value;
var denominator = +getField("Text3").value;}
// Calculate and set this field value
if (denominator == 0)
{
event.value = numerator / denominator;
}
else {
event.value = "";
}
}

Now I am getting a syntax error 2: at line 3

This still has a lot of the issues we described... Try this:

if (Number(this.getField("Text3").value) == 2) {
	var numerator = Number(this.getField("undefined_10").value);
    var denominator = Number(this.getField("Text3").value);
	if (denominator == 0)
		event.value = "";
    else event.value = numerator / denominator;
} else {
	event.value = "";
}

Thank you. I have tried this, but I am still not getting the desired results.

For further information, the "Text3" field is populated by default as blank or, if a check box is checked, populated with the number 2. The check box portion is working fine, but when the box is checked and I am getting a result of blank, but when the check box is UNchecked, I am getting the result that I actually need. I don't know if the check box is causing an issue. I've attached a screenshot of the project that will hopefully help.

I appreciate your help.

In addition to the correct comments made above, you need to define what should happen if the value of the first field is not 2. If you don't do anything then the current value will remain as it was, which is probably not what you want to happen, unless you want the user to be able to fill in a value manually in that case.

I would like it to return the field as blank. How do I accomplish this?

At the end of the code add this:

else event.value = "";

Also replace "!=" with "==".

Is "Tex3" the correct field name?

Initialize variables outside 'if' statement, or it will throw an error when 'if' condition is not met, and it tries to calculate.

My apologies. The field name should be "Text3". I caught that and corrected it right after I posted (of course), but my results were the same.

Can you explain or give an example of what you mean by "Initialize variables outside 'if' statement"? I'm terribly new to all of this.

Pay attention to field name because "Text1" and "text1" are not same.

Use this:

var t1 = Number(this.getField("text1").valueAsString);
var t2 = Number(this.getField("text2").valueAsString);
var t3 = Number(this.getField("Text3").valueAsString);

if(t3 === 2){
 if(t2 !== 0)
  event.value = t1/t2;
 else
  event.value = "";}
else
 event.value = "";
