OK that all works correctly now... the problem comes in when a user goes back to the original drop down list and selects something else, I need the repeating group to drop all of its values and load a new set, because the previous values still come up... I tried to delete the values, but i just ended up with an object null exception....

So all I did was copy and paste the exact same code into the changed event. I have attached my code the 5th line of code "nav.SelectSingleNode("/my:myFields/my:SectionA/my:names", NamespaceManager).SetValue("")" gives me the following error: Operation is not valid, because of the current state of the object.

Is there anything special I would need to do in order to access and add new values in the drop down list.
