Acrobat Pro DC Random Form Field

I have a 2 page form PDF. Page 1 has 3 form fields in it named 'Word1' 'Word2' and 'Word3' and a button.

On page 2 I have just one form field.

What I want to do is have the single form field on page 2 randomly select one of the page 1 form fields when I press the button on page 1.

Is this possible to do with a script? I haven't inserted any scripts into Acrobat Pro DC before, so I'm hoping someone can give me an example script to run for the form field on page 2 and the button on page 1. Thank you in advance for any help!
