Hi John,
"How do you populate the listbox? How does the data in the child table get changed?"

Have got a field for each field in the listbox directly above the listbox. Pressing add,change,or delete buttons enables changes to those fields. When complete, update the child table with replace . . .with . . . for changes and insert into . . . for Adds. then thisform.refresh to update data in listbox. That part works fine, its just when I press the save or revert button on the navigation bar that it doesn't work. Can open a browse window for the child table while still in the form and it reflects the changes. However, when close the form and open the browse window again, it shows the origional data.
I figured wasn't giving enough info in first thread.
