I have a requirement where the history of a particular date field is recorded over time on a form. The field can be changed by the user but every time the date is changed I want to write the previous value in the date field to a text box on the form.
For example, if the date currently set is 1/1/2017 and the user then changes this date to 1/2/2017, 1/1/2017 is written to my text box. Is someone able to tell me the easiest way to do this please?
Many thanks for your help in advance.
