How to pass url parameter value to a form's text field

How to pass url parameter value to a form's text field

Hi,

I have been searching for ages but I couldn't find it.

I have a stateless form (but stores record in Customer View)
After filling up the form, there is Submit and Add Record so it's redirected to another HTML form (with embedded zoho form) using this url. I succeeded on this.

https://creator.zoho.com/christianjoy/sample/#View:Add_Session? CustID=789456233

My Problem:
In my Session Form (inside Add_Session HTML View), i have a Customer_ID text field.
How do I fetch the  CustID=789456233 from the url and pass the value to the customer_ID text field on load?



I need this to link the Session View to my Customer View

Customer:

ID
Name
Email
Address

Session:

Customer_ID
Session_ID
Tech_Name
Result

Thanks,

CJ
