InfoPath Dev

Hi all,

In the infopath form I am designing, I have enabled the form to submit the data to a custom list via web services and then submit the form to the form library.

What happens next is the next user will be notified via email and will update the next section of the form and again, once he hits submit the form will submit to the list and save the form back to the form library

The issue that I am having is that the form will submit replica pieces of data to the list because I don't know how to get the form to find the corresponding item in the list and update it.

Does anyone know if this is possible or could guide me in achieving this for my form?

I have added the code for the initial submit using C# and my form is an infopath filler form.

Thanks in advance,

R

string ListName = root.SelectSingleNode("/my:myFields/my:ListName", NamespaceManager).Value;

string taskNumberStage = root.SelectSingleNode("/my:myFields/my:TaskNumberStage", NamespaceManager).Value;

string groupTaskNumber = root.SelectSingleNode("/my:myFields/my:GroupTaskNumber", NamespaceManager).Value;

batch.SelectSingleNode(

"/Batch/Method/Field[@Name='GroupTaskNumber']", NamespaceManager).SetValue(groupTaskNumber);
