Is it possible that when a user open up a form (reader extended), and upon clicking a button, delete away certain fields in the form, like a textbox or subform. And when user save and reopen the form, the deleted fields will not appear. Possible? Thanks.
Then the only other way I can think of is to have two different templates and export the data out of the 1st one and import it into the second one. If the fields are not in the second one then the data for those fields is ignored.
You can also set a new hidden field value to a new value after the button is clicked. Then in the initialize of the form you can hide those fields by looking at the given hidden value.
