Automation Error : unspecified Error

[Loganayaki]

Hi,

I am writing the excel vba code for Login functionality. Somehow i have searched this forum and written the code. But i am getting "Automation error: Unspecified error". Please help me to resolve this .
When i do debug the yellow marker show the line "Set doc = IE.Document " which is red marked in code below . I am using 2010 excel and added HTML library and Internet controls library under tools -> preference

Option ExplicitSub CommandButton1_Click()


Const cURl = "Replaced with My URL "
Const cUsername = "My username"
Const cPassword = "Mypwd"


Dim IE As InternetExplorer
Dim doc As HTMLDocument
Dim Loginform As HTMLFormElement


Dim UsernameInputBox As HTMLInputElement
Dim PasswordInputBOx As HTMLInputElement
Dim SigninButton As HTMLInputButtonElement
Dim HTMLelement As IHTMLElement


If IE Is Nothing Then Set IE = New InternetExplorer
IE.Visible = True
IE.navigate cURl


Do While IE.Busy
Loop
Do While IE.readyState = READYSTATE_COMPLETE
Loop


[COLOR=#ff0000]Set doc = IE.Document[/COLOR]


Set Loginform = doc.forms(0)
Set UsernameInputBox = Loginform.elements("USERID")


UsernameInputBox.Value = cUsername




Set PasswordInputBOx = Loginform.elements("user_pwd")


PasswordInputBOx.Value = cPassword


Set SigninButton = Loginform.elements("fc_sbmit")


SigninButton.Click


Do While IE.Busy


  Loop


  Do While IE.readyState = READYSTATE_COMPLETE
  


  Loop
Set doc = IE.Document




End Sub
