If I understand your question, you want to be able to dynamically (programmitically add values to the list?

Create a list item but leave don't populate the values. Check the list elements values to ensure the list is empty. Form should compile and run. They field should show up as a drop-list with allowing for NULL. After that set up a trigger to populate that list at run time. Check out the following built-ins:

ADD_LIST_ELEMENT
DELETE_LIST_ELEMENT
POPULATE_LIST Received on Fri Feb 13 1998 - 00:00:00 CET
