yes a data base would need to be used in order to keep track of the number to get the right increment.
create a database table and use the Data Assist Insert record behavior to store the form data .
the insert record behavior stores the ID of the record that is inserted to a session variable.
you could use the session variable to show the incrementing number.
after you create the table, you can run the following query:
ALTER TABLE tblName AUTO_INCREMENT = 8302;
this will set the starting point of the auto increment to 8302
