Chuck,
It's the 3 letter prefix for combobox. Check the help file under naming conventions for a list of them.
If you put the parent table at EOF() then everything should be empty. But if the cbo is bound to a field in the parent table it'll be disabled. So you'll have to unbind it from the field.
>Thanks David ... I would like to just make everything come up blank (where no record is being pointed at), and just have the user start like that ... with a clean slate. You state, "If you cbo is not bound to a parent table field then it'll show up empty or to whatever value you initialize it to. You can set the cbo.Value to reflect the first parent table record."
