is it possible to use a deluge statement to affect a field on a stateless form after clicking a button?

example

I am inserting data into a from a stateless form.  however, once i submit the record, i want to keep some data in some fields in the stateless form and reset other fields to null or empty.  so i do not have to reload the entire form and reselect or enter the same information. 

Make sense?
