I got that to work just using this code in the change event of the drop
down list and changing the settings of the table. var iRows =
xfa.event.newText;TravelPlans.TravelTable.TravelRow1.instanceManager.setInstances(iRows);Now
my problem is once I select 0 (zero) from the list and the last row is
removed, It will not reappear when I select any other number.
