I guess this is more of a best practices kind of question.
A filler has entered a bunch of data in a subform. They then change an earlier option which causes that subform to disappear and a different one to appear.
As well as setting mandatory fields off and on, what are people doing with the previously entered data? Leave the data alone or blank the data? Are there any problems with data in hidden subforms when it comes to exporting XML or anything like that?
The downside I can see to blanking the data is that if the filler changes their mind again they would have to re-enter the data.
