>I have two listboxes with RowSourceType set to SQL. The first listbox shows available parents while the second shows the children of the selected parent that are associated with the local station. I want to modify the SQL statement of the first box so it does not show items that don't have children. Here are the SQL statements:

> WHERE ( taskID = curTasks.taskID .AND. ;

First ListBox:
SELECT taskID,task ;
FROM tasks ;
ORDER BY task ;
WHERE (active = .T.) ;
AND taskid IN (Select taskid From subTasks) ;
INTO CURSOR curTasks
