I have a fillable form where I input a persons age. How can I make this form calculate the persons age from their date of birth. I have added a field that calculates todays date automatically. I have tried a simpel Today - DOB but am not getting an number. I am getting NaN as my result. Any help would be great.
There is no direct option to calculate the current age depending on the two dates. However, you may use a script to calculate this. Please refer to the suggestions provided on the following community threads with similar discussions:
