I have a secondary Datasource, which performs a lookup to a sharepoint list to pull down info. This datasource is used to populate a dropdown box for a list. What I was attempting to do, was after the user selects a value for the dropdown box, use that to populate a repeating table with all entries that are valid for that entity. I created a changed event in my code and did the following &quot;, i.e. &quot;@First_Name&quot; in one of them. If I try that infopath raises an exception. What does the &quot;@ do in the examples posted? I used the Copy Xpath function from my secondary datasource in order to fill in the location on my rows.current.selectsinglenode() calls. 3. Am I doing this in a totally stupid way? Is there a way to filter this datasource programmatically? In the infopathdev forum post I linked above Hilary Stoupa suggests a method, but I can&#39;t seem to get it to work. Of course, that could be all related to the issues I&#39;m having already? Does anyone have any help or insight available into what I am doing wrong here? I&#39;ve been staring at this for several hours and am not making any headway &gt;.
