Error while inserting data

Hi,

I'm trying to add data from Form A to Form B, I have added the script in Form A "on edit - on success".

Form name explanation:

Form A = To_Do_Form
url - https://creator.zoho.com/appbuilder/piju2111/penta-crm-11/form/To_Do_Form/workflow/edit

Form B = P_L
url https://creator.zoho.com/appbuilder/piju2111/penta-crm-11/form/P_L/Sales_Ticket/workflow/edit

Script in Form A:

insert into P_L
            [
                Purchase_Date = input.Closed_Date
            Purchase_Ticket = input.Ticket_No
                Purchase_From = input.Customer_Name_Lookup
                Total_Purchase_Amount = input.P_Amount
                Added_User = zoho.loginuser
            ]

Here I'm getting error - On success - in field Purchase_Ticket, this is the lookup field on Form B.

For testing you can edit my record with Ticket: 14152312 for testing purpose.

Note edit access given to support.

Thanks
