Calling a function inside a sub routine

Hello friends,
After several searches on google, it looks this is one of the best places to get VBA Excel help.
I am trying to login to different websites automatically. The goal is to create a function that will handle all repetitive tasks and then call it inside the sub routine, so the code for each different website login will be shorter.

First here is the code that is currently working for one test website "FaceBook":

Sub OpenFacebook()Dim ie As Object
Set ie = CreateObject("InternetExplorer.Application")
ie.navigate Sheets("Sheet1").Cells(2, 5) ' Sheet1, Row 2, column 5 has the Link to FaceBook
ie.Visible = True
Do While ie.Busy And Not ie.readyState = 4
DoEvents
Loop
DoEvents
On Error Resume Next
ie.document.all.Item("email").Value = Sheets("Sheet1").Range("B2") ' Cell "B2" in Sheet1 has the user name
ie.document.all.Item("pass").Value = Sheets("Sheet1").Range("C2") ' Cell "C2" in Sheet1 has the password
ie.document.all.Item("loginbutton").Click
End Sub

I tried to create a function/private sub called "OpenLink" that could handle the repetitive tasks as shown below, but it is not working:

Private Sub OpenLink(ByVal url As String, ByVal isVisible As Boolean)
Dim ie As Object
Set ie = CreateObject("InternetExplorer.Application")
ie.navigate url
ie.Visible = isVisible

Do While ie.Busy And Not ie.readyState = 4
DoEvents
Loop
DoEvents
End Sub

And then I am including "OpenLink" in the sub routine:

Sub OpenFacebookTest()
OpenLink Sheets("Sheet1").Cells(2, 5), True
On Error Resume Next
ie.document.all.Item("email").Value = Sheets("Sheet1").Range("B2")
ie.document.all.Item("pass").Value = Sheets("Sheet1").Range("C2")
ie.document.all.Item("loginbutton").Click
End Sub

When I step through it, it does not show me any errors, but it does not automatically enters the user name and password in the fields and the submit button is not clicked.

Any help you can provide will be greatly appreciate it.
Thank you
