Yuan,
Thanks again. I went with a different approach, adding "Events" as the main list and then "EventTasks" as the child list, linked by [Parent].[ID] = [Child].[EventID]. The new qListView looks fine, but I'm having problem setting the color and bolding the fields. Do you have any documentation on how to set the styles for Grid Appearances? Also, the filter options are now based on parent fields instead of child fields. Is there a way to filter by child fields? Thank you.
