Change Form events are added to an environment 
before any text block editing or
text block events are applied to the data.
When would I use a Page/Para Change Form
event?
The PARIS Designer offers both Page/Para Change Form events and Local Text
Block Change Form events.
For reasons of control, it is better to conduct form changes in text blocks as local
text block events. Remember, any type of Page/Para event is conducted on 
every
text block on a page, whereas a local text block event is conducted on its associated
text block only.
For example:
For instance, if you know the condition to test for (such as the words ‘Water
Sports’), but don’t know where on the page it will appear, you would use a
Page/Para Change Form event.
In a case where the words ‘Water Sports’ could appear in any text block on a
page, but you only want to change the form when ‘Water Sports’ appears in the
‘Favorite Activities’ text block, you would use a 
Local Text Block Change
Form event. You would conduct the form change test in the ‘Favorite Activities’
text block as a local text block event.
