Yes, been using MM for a couple of years, just never ran into this problem. Pages 87-90 are dog-eared from turning them so many times!

I checked the order of requerying the bizobj's and comboboxes and got it working better. However, the controls are still blank immediately after the form instantiates. After the initial selections of each of the comboboxes, they will refresh correctly. One other peculiarity: if the second or third choice within the child combobox is selected, and then a new parent choice is selected, the child box will go blank. hmmm...

Thanks for your help, all suggestions are appreciated
