I&#39;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 &quot;Req Number&quot;. This is a look-up field to a field of the same name in the parent list. I&#39;ve got to the point where when I create a new child form item I can choose which &quot;Req&quot; is available, however, I need it to filter from the child. If the parent &quot;Req&quot; field = 21, I need the look-up field to display 21 when I create a new child item. I&#39;m doing this with IFS 2010. Hopefully I&#39;ve explained this well enough. Thanks again!<br /></p>
