I have a "parent" list and a "child" list. The child list has a lookup to a column in the parent list. I've placed a Related Item View on the parent list DispForm.
When a user is viewing the DispForm, they can click Add New in the Related Item view, to add a new child item. But the value of the parent item is not passed to the child NewForm.
Any suggestions on how to achieve this (I do have SPD).
