Click this btn in Ie web page

[Mepwnz2010]

I'm trying to automate a web page for work, and up until a week ago I didn't even know what VBA is. I've got as far as checking all the cells to make sure the user filled them out and then pulling the web page to the focus of the macro. Next I need to click a btn and ultimately I will need to click a few btns operate some drop down boxes and fill in some text. I've been working on this button for a while and I don't seem to be getting anywhere. I can't link the url cause its for work, and you would need a log in anyways. But I i will link my macro code used so far, and the code for the button.

' Arguments:
'  Title    -  title of the searchied IE window
'  [IsLike]  -  False/True = exact/partial searching, default is False
'  [IsFocus] -  False/True = don't_activate/activate IE window, default is False
Function GetIeByTitle(Title, Optional IsLike As Boolean, Optional IsFocus As Boolean) As Object
  Dim w As Object
  For Each w In CreateObject("Shell.Application").Windows
    With w
      If .Name = "Windows Internet Explorer" Then
        If IsLike Then
          If InStr(1, .LocationName, Title, vbTextCompare) > 0 Then  ' ZVI:2013-09-10 fixed
            ' Partial title of window is found - activate IE window
            If IsFocus Then
              w.Visible = False
              w.Visible = True
            End If
            Set GetIeByTitle = w
            Exit For
          End If
        Else
          If StrComp(.LocationName & " - " & .Name, Title, 1) = 0 Then  ' ZVI:2013-09-10 fixed
            ' Title of window is found - activate IE window
            If IsFocus Then
              w.Visible = False
              w.Visible = True
            End If
            Set GetIeByTitle = w
            Exit For
          End If
        End If
      End If
    End With
  Next
  Set w = Nothing
 
      
End Function
