Enter and update data in a form - Nepali

On clicking a button activate a trigger that copies the previous value of the field to a another field and saves the changes in current field.
I have a table address and another table prev. address, When I update the values of the table address and save. I want the previous value of the table address to get copied in the prev. address table so that I can have a record of the last change made along with the time stamp.In this case when I change the value of the address and click on the save button the address before modification should get copied to the prev address table.
