Check if value in a form field is empty or not

Hello friends! I have this question, please help me.

I have a simple form in Flowable Design with two fields, name and age.
Name is mandatory field and age is optional.
Like this picture:

Now, I want to print those 2 fields in a word document via flowable engine.
Like this:

But age field cause it’s optional, if the user not fill this in the form, I do not want
to print in doc file nothing, neither the value in the right, neither the field name in the left.

Please help me with the if condition!
