Reading web data with VBA from excel using Microsoft HTML Object Library and Microsoft Internet Controls

Description:
This is a sample script showing how I pull web-banking balances off the internet when I want to have a total picture of how my finances are. For the boring reasoning go to the last page. Otherwise technical details follow.
Project References:
Add the following to the references for this to work:
-Microsoft HTML Object Library
-Microsoft Internet Controls

Code:
The code below is an example of how to do this missing error handling. As it uses IE, it saves the developer the task of implementing SSL in VBA.
Navigating the Site
Public oBrowser As InternetExplorer
Sub Login_2_Website()
Dim oHTML_Element As IHTMLElement
Dim sURL As String
Dim text As String
Dim avarSplit As Variant
sURL = "https://secure.alpha.gr/e-services"
Set oBrowser = New InternetExplorer
oBrowser.Silent = True
oBrowser.navigate sURL
oBrowser.Visible = True
Do
' Wait till the Browser is loaded'
Loop Until oBrowser.readyState = READYSTATE_COMPLETE
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_NewLayoutSignOn__userName").Value = "USER"
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_NewLayoutSignOn__Pswd").Value = "PASSWORD"
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_NewLayoutSignOn__login").Click
Do
' Wait till the Browser is loaded'
Application.Wait DateAdd("s", 0.1, Now)
Debug.Print (oBrowser.document.readyState)
Debug.Print (oBrowser.LocationURL)
Loop Until oBrowser.document.readyState = "complete"
oBrowser.navigate "https://secure.alpha.gr/e-services/AWBPage.aspx?service=balancesStatements"
Do
' Wait till the Browser is loaded'
Application.Wait DateAdd("s", 2, Now)
Debug.Print (oBrowser.readyState)
Debug.Print (oBrowser.LocationURL)
Loop Until oBrowser.document.readyState = "complete"
Application.Wait DateAdd("s", 2, Now)
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_balancesStatements__productsPagedDropDownList__selectionList").selectedIndex = 1
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_balancesStatements__productsPagedDropDownList__selectedIndexHiddenField").Value = "1"
oBrowser.document.all.Item("_contentPlaceHolder__loadedControl_balancesStatements__balancesButton").Click
Do
' Wait till the Browser is loaded'
Application.Wait DateAdd("s", 0.1, Now)
Debug.Print (oBrowser.document.readyState)
Debug.Print (oBrowser.LocationURL)
Loop Until oBrowser.document.readyState = "complete"
getBalance
End Sub
Analysis follows on next page
