How to get after form submission value?

Hi,

Am using contact form on Squarespace. After form submission gets all values in a javascript file.

Tried below ways:

POST-SUBMIT REDIRECT -> http://rpadmanaban-dev.apptivo.net/create.js

This field did not accept the script file

Another Way:

Code injection fields ->this script called the form reload functionality. I need after submission called the script file

I’m not 100% clear on what you’re trying to achieve here, but think this might be of help to achieve a redirect
