Hi,
Not quite sure how to go about this, any help would be appreciated. I've got two SharePoint lists (a parent and a child). There is a certain field that I want to have in all child lists that I create called "Req Number". This is a look-up field to a field of the same name in the parent list. I've got to the point where when I create a new child form item I can choose which "Req" is available, however, I need it to filter from the child. If the parent "Req" field = 21, I need the look-up field to display 21 when I create a new child item. I'm doing this with IFS 2010. Hopefully I've explained this well enough. Thanks again!
