How to get ID of item after being redirected to a new form using a button

Hello,

I am new to Zoho Creator and Deluge script, hoping for some assistance. I have created a report where I added a "Notes" button. 



I have created a workflow where the "Notes" button should redirect me to a new form below.
   
My question is how can I fetch and auto-populate the "Assignment ID" field with the ID of the assignment I clicked from the report table?
