Need to create Application "Call to Support".

Need to create Application "Call to Support".

I am using Zoho Creator for making an application "call to Support" which will create a ticket in Support. When the ticket in Support is closed, its status should be communicated back to Creator. Then, we will work on the same process with CRM.

I have created form of Ticket. But I need to add auto reference number for each submitted ticket. How can I add this?
After submitting this ticket, I need to show ticket status like open or close. How can I add this option to show ticket status?

I need a page, where customer will login by ticket reference number to see ticket status. How can I do this?

Please help me step by step.

Thanks!
