Calculated age is not rendering in Fillable pdf Form

Hi, I have calculated childs age based on Current Date - BirthDate as per article http://form.jotformpro.com/form/41556714288967

This works well within Jotforms but when you render the form using fillable pdf form  http://www.jotform.com/fillable-pdf-form-creator/ the age field does not render. 

Your assostance greatly appreciated   Thank you

Hi,

Unfortunately, calculated form value doesn't work on PDF's. This is one of the limitation of PDF's.

Do let us know if you need further assistance.
