Precompile a field in a Form

Hi, Please I desperately need Help!
I would have the need that when the user enters a value (numeric) in the appropriate field pods on the backend wordpress page, that value was used to precompile a field of gravity forms (used on that same page). I have obviously already inserted the pods field inside the post but I can’t connect it with Gravity Forms.
I searched everywhere and tried in every way to make this connection but I just didn’t succeed.
Would you please help me with this very important thing for me?
Please…
