Calculating age to a specific date

[Johnthomp2]

I have a file that calculates someones age to the current date.  In one field you type the date, and in the other the age appears.  I need it to calculate a persons age at October 1, 2010 instead of the current date.  I do not know how to attach the file so here is the xml code as it appears in LiveCycle

Take a look at the attached. I think I have it right although my FormCalc skills leave something to be desired.

// form1.page1.ageAsOfDate::calculate - (FormCalc, client)

if (HasValue(dob)) then

  if (HasValue(selectedDate)) then

    var selectedDate_ = Date2Num(selectedDate.formattedValue, "MM/DD/YYYY")

    var dob_ = Date2Num(dob.formattedValue, "MM/DD/YYYY")

    var diff = selectedDate_ - dob_

    $.rawValue = Floor(diff / 365.25)

  else

    $.rawValue = null

  endif

else

  $.rawValue = null

endif

Hey, this works really great and I have a follow up question.  I set the date to calculate someones age as of October 1, 2010.  When they type in their birth date, that age pops up in the age box.  I want to use the age that pops up in that box to control some radio buttons later in my document.  For example, if they are under the age of sixteen, then certain buttons will be disabled.  The only way I can get this to work is to have the person click on there age after it is auto calculated.  That clicking activates the disabled command.  I want the command to initialize immediately after they type in there birthdate.  I only want the field where they can enter their birthdate on my form.  The rest will be invisible.  Is there a way to do that?  Thanks for your help.

Added a button and the following on the button calculate event...

// form1.page1.btn::calculate - (JavaScript, client)

form1.page1.btn.access = "open";

var age = parseInt(form1.page1.ageAsOfDate.rawValue);

if (age < 16) {

  form1.page1.btn.access = "protected";

}

Nearly there!  Many thanks for your simple little formula.  I got it working as follows:

if (HasValue(Page1.studentdetails.dob)) then
   if (HasValue(rdtestdate)) then
      var rdtestdate_ = Date2Num(rdtestdate.formattedValue, "DD/MM/YYYY")
      var dob_ = Date2Num(Page1.studentdetails.dob.formattedValue, "DD/MM/YYYY")
      var diff = rdtestdate_ - dob_
      $.rawValue = Floor(diff / 365.25)
   else
   $.rawValue = null
   endif
else
$.rawValue = null
endif

What I need is to report the results in terms of years and months rather than round to years only.  How can I get the result to be formatted as years and months?

Many thanks for your assistance!
