Default Infopath has invalid token

How do I retrieve the correct ID in a SharePoint List using vb code after submission and after the form has been signed. I am trying to read and populate the ID field in my form so it can be printed out with a unique ID in that field.

I have the data connection setup correctly, but right now it only returns the first ID in the list. I don't necessarily want the last one in the list, because it may or may not be the last ID in the list. Please help!

This is a browser enabled form.

I am using the following code: but get the invalid token error

' Retrieve the value of the control number
Dim TSRNum As String = xnMyForm.SelectSingleNode("/my:myFields/my:TSRControlNum", ns).Value

' Retrieve a reference to the SharePoint list
Dim xPath As XPathNavigator = DataSources("TSRData").CreateNavigator()

' Search for the id in the SharePoint list
Dim SharePointID As XPathNavigator = xPath.SelectSingleNode("/my:myFields/my:TSRControlNum[@TSRID", ns)
'Dim SharePointID As XPathNavigator = xPath.SelectSingleNode("/dfs:myFields/dfs:dataFields/dfs:TSRData/@TSRID[ /my:myFields/my:TSRControlNum = current()]")

'Check whether the search returned a result
Dim IDRes As String = String.Empty
If SharePointID IsNot Nothing Then
IDRes = SharePointID.SelectSingleNode("@TSRID", ns).Value
End If

xnMyForm.SelectSingleNode("/my:myFields/my:TSRControlNum", ns).SetValue(IDRes)

Thanks for any help.
