Unable to Resolve Script Error Message

Question

Hi,
I am using Windows Vista and Acrobat Adobe Extended Version 9.
I am struggling with a script. I am sure it is something simple; however, I am struggling mightily with it. I am getting an error message, shown below, that I am unable to understand and resolve.
I am trying to calculate age when given a birthdate. I used "Search" to find a script here at Adobe forums.
Here's the script that I am using:
StoneG, "Third Time Lucky to get Age from DOB entry" #1, 24 Oct 2006 7:21 am
// Jared Langdon
// J. Langdon Consulting
// www.jlangdon.ca
// DOB = Date of Birth
var strDOBYear = Birthdate.rawValue.substr(6,4);
var strDOBMonth = Birthdate.rawValue.substr(0,2);
var strDOBDay = Birthdate.rawValue.substr(3,2);
var oDOB = new Date(parseInt(strDOBYear,10), parseInt(strDOBMonth,10)-1, parseInt(strDOBDay,10) );
var oToday = new Date();
// determine whether the person's birthday has already occurred this year
var bBirthdayHasOccurred = false;
if (oDOB.getMonth() < oToday.getMonth()) bBirthdayHasOccurred = true; if ((oDOB.getMonth() == oToday.getMonth()) && (oDOB.getDate() <= oToday.getDate())) bBirthdayHasOccurred = true;
var nCurrentAge = 0;
if (bBirthdayHasOccurred)
nCurrentAge = oToday.getFullYear() - oDOB.getFullYear();
else
nCurrentAge = oToday.getFullYear() - oDOB.getFullYear() - 1;
this.rawValue = nCurrentAge;
==========
I changed the script slightly. I changed from:
var strDOBYear = DateOfBirth.rawValue.substr(6,4);
to
var strDOBYear = Birthdate.rawValue.substr(6,4);
My variable is "Birthdate".
And I changed boolBirthdayHasOccurred to bBirthdayHasOccurred.
Upon opening the file in Acrobat 9, my error messages is as follows:
Acrobat JavaScript Debugger Functions Version 9.0
Acrobat EScript Built-in Functions Version 9.0
Acrobat Annotations / Collaboration Built-in Functions Version 9.0
Acrobat Annotations / Collaboration Built-in Wizard Functions Version 9.0
Acrobat SOAP 9.0
Birthdate.rawValue has no properties
8:XFA:form1[0]:#subform[0]:Age[0]:calculate
The line above repeats several times. And then...
boolBirthdayHasOccurred is not defined
19:XFA:form1[0]:#subform[0]:Age[0]:calculate
boolBirthdayHasOccurred is not defined
19:XFA:form1[0]:#subform[0]:Age[0]:calculate
Birthdate.rawValue has no properties
8:XFA:form1[0]:#subform[0]:Age[0]:calculate
Birthdate.rawValue has no properties
I have no idea why it mentions "boolBirthdayHasOccurred" because that text is not even present. The last two lines repeat more several times.
When I have delete this entire script, the problems disappears. I have tried finding "boolBirthdayHasOccurred" without success.
Can someone point me in the right direction to troubleshoot this problem?

Kevin

Hi Paul,
>>The default would be the format that your machine has set.
That's interesting. So the users' machines are very likely different than mine. So there's no way of knowing in advance. That would seem to make the routine suggested by Jared Langdon (see my top post in this thread) somewhat troublesome? If users' machines are set differently than his, then his routine wouldn't work?
I learned two important items with this task:
1) I need to somehow specify (as done by Stephen) the format of the date numbers before I use them;
2) Rather than using the Calculation Event on the Age, I should instead use Exit Event on the Date-of-Birth field.
Thank you for your response.

Kevin
