Wayne,
I've put the original code back in the code property and have the same results - nothing returns. However, now that it's back to your code - is there anything on the sql server that needs to be set to allow XML?
Function ReturnXML(ByVal MultiValueList As Object, ByVal Root As String, ByVal Node As String, ByVal Element As String) As String
Dim ReturnString = ""
Dim sParamItem As Object
ReturnString = " "
For Each sParamItem In MultiValueList
ReturnString &= " "
Next
ReturnString &= " "
Return (ReturnString)
End Function
