Код работает нормально, когда я получаю доступ к функции из VBA, однако, когда я вызываю ту же функцию в ячейке Excel (postalcode("23.0776120,72.6538530"), Я получаю ошибку #Value. Мой код:

Function PostalCode(latlng As String) As String

Dim xmlDoc As MSXML2.DOMDocument60
Dim xEmpDetails As MSXML2.IXMLDOMNode
Dim xParent As MSXML2.IXMLDOMNode
Dim xChild As MSXML2.IXMLDOMNode
Dim Col, Row As Integer

Set xmlDoc = New MSXML2.DOMDocument60
xmlDoc.async = False
xmlDoc.validateOnParse = False
' use XML string to create a DOM, on error show error message
If Not xmlDoc.Load("https://maps.googleapis.com/maps/api/geocode/xml?latlng=" & latlng) Then
    Err.Raise xmlDoc.parseError.ErrorCode, , xmlDoc.parseError.reason
End If

Set xEmpDetails = xmlDoc.DocumentElement
Set xParent = xEmpDetails.FirstChild

Row = 1
Col = 1

Dim xmlNodeList As IXMLDOMNodeList

Set xmlNodeList = xmlDoc.SelectNodes("//formatted_address")

 Worksheets("Sheet1").Cells(1, 6).Value = xmlNodeList.Item(0).Text
 Dim xyz As String
 PostalCode = xmlNodeList.Item(0).Text
' PostalCode = "Not Found (try again, you may have done too many too fast)"
MsgBox PostalCode

End Function
