VBA to log into website to extract data

Hello all, I am working on a VBA code to sign into a website and extract data from that said website. The below code is what i have so far. Things that I know are incorrect: entering the username does not process. I have a feeling that it has to due the HTML code of the website and I am just not familiar with using VBA to manipulate IE at all. However, the password part works just fine. Secondly, I do not know how to trigger the "login" button. Any help would be greatly appreciated. This is all code that i have compiled from my research in understanding the subject.

URL: https://live.barcap.com

Sub Login()
 
Dim appIE As Object ' InternetExplorer.Application
Dim sURL As String
Dim UserN As Object ' MSHTML.IHTMLElement
Dim PW As Object ' MSHTML.IHTMLElement
Dim Element As Object ' HTMLButtonElement
Dim btnInput As Object ' MSHTML.HTMLInputElement
Dim ElementCol As Object ' MSHTML.IHTMLElementCollection

 
Application.ScreenUpdating = False
 
Set appIE = CreateObject("InternetExplorer.Application")
 
sURL = "https://live.barcap.com"
 
With appIE
    .Navigate sURL
    ' uncomment the line below if you want to watch the code execute, or for debugging
    .Visible = True
End With
 
' loop until the page finishes loading
Do While appIE.Busy
Loop
 
' enter username and password in textboxes
Set UserN = appIE.Document.getElementsByName("user")
If Not UserN Is Nothing Then
    ' fill in first element named "username", assumed to be the login name field
    UserN(0).Value = "xxxxx"
End If
 
Set PW = appIE.Document.getElementsByName("password")
' password
If Not PW Is Nothing Then
    ' fill in first element named "password", assumed to be the password field
    PW(0).Value = "xxxxx"
End If
 
' click 'Submit' button
Set ElementCol = appIE.Document.getElementsByTagName("INPUT")
 
' loop through all 'input' elements and find the one with the value "Submit"
For Each btnInput In ElementCol
    If btnInput.Value = "Submit" Then
        btnInput.Click
        Exit For
    End If
Next btnInput

End Sub

Hi,

'cause button gets an ID ("submit"), use getElementByID statement instead of a bad loop on Value !

If you fail, post your IE version and your OS version …
