Notify user when a second page is generated

Hi all,

I have a form with three tables. Users are able to make these tables appear and disappear on a click event. They are also able to add rows to these tables again on a click event.

Because of the two possibilities below, this form will at times spread to a second page.

The overseer of our forms development project would like to be able to notify the user when the page expands on to the second page.

Can anyone tell me how to generate a message box only in the event that a second page is generated?

Please keep in mind that I'm a newbie to both Livecycle and JavaScript.

Thanks in advance!
