Display alert if text field is blank

Are you getting any error listing in the JavaScript debugging console?

Make sure you are spelling and capitalizing everything properly.

Are you sure a null string is the same as null?

Try the following script:

console.clear();
console.println('null == "": ' + (null === ""))
try {

If (this.getField("bene1_name").value == "")
{
app.alert("You have not entered a name for the beneficiary in Section 10. Please note, Section 10 is required. Be sure to fill in the beneficiary information before you submit the application. If you have questions, please call xxx-xxxx.", 3, 0, "Form Completion Instructions");
}

} catch(e) { console.println(e.toString()); }

The debugger says...

When I cut and paste the script I get the following on the JS debugging console:

null == "": false

So 'null' is not the same as a null string ("").

There is no 'If' statement in JavaScript, but there is an 'if' statement.

You also have some other syntax errors. But without seeing the code it is hard to specifically tell you what is wrong.

Oh thank you. The capital I in If was the problem. I changed it to lower case and now it works. Thanks again!!

Well, I guess I was wrong. It displays the message whether the field is blank or not.

I had added a semi colon after the if and that was not correct. Here is my final working script...

if (this.getField("bene1_name").value=="")
{
app.alert("You have not entered a name for the beneficiary in Section 10. Section 10 is

required. Be sure to complete beneficiary information before submitting the application.

If you have questions please call xxx-xxxx.", 3, 0, "Form Completion Instructions");
}

To be on the safe side, you can check for either null or the empty string, like so:

if (this.getField("bene1_name").value == null || this.getField("bene1_name").value == "") {
