Is it possible to auto-populate quantity field value from a number field value or value from nested forms merge tags?

Question

I'm trying to auto-populate the quantity field based on the total selected checkboxes from my nested forms.

Using Gravity Forms checkbox count:https://gist.github.com/spivurno/a14ef4a18f57d0c67811e1b4d8791781 ,I already created a merge tags that I can calculate the total selected checkboxes and put this value into a number field in the parent form. This is my merge tag: {Add a Location:25:sum=4}

Now I'm trying to apply this value in the quantity field in the main form. Is it possible?

Another one of our plugins is super useful when wanting to copy the value of one field to another. It's called Gravity Forms Copy Cat:
