Internet Explorer VB Control - Accessing Frames

Hello,
We've been given a website to access to retreive our POD but we have to login each time and then enter in the reference. We have an access database that ahs the reference so i'm looking for a way to automate the login and search. I've looked round and have written the following code:

Private Sub GetPOD_Click()

    Dim IE As InternetExplorer

    Set IE = CreateObject("Internetexplorer.application")

    IE.Visible = True

    IE.Navigate "http://www.xxxxxxxxx"

    'This will wait complete page download...

    Do While IE.Busy

      DoEvents

    Loop

    IE.Document.frames(1).Document.form1.T1.Value = "xxx"

    IE.Document.frames(1).form1.T2.Value = "xxx"

    IE.Document.frames(1).form1.T3.Value = "xxx"

    IE.Document.frames(1).form1.submit

End Sub

The webpage that has the login script is framed and we want to access the frame called main. I didn't develop the website so I can't change anything.

The basic question I'm asking is "How do I enter in data into a form and submitted located in a frame"

Please help

Thanks

Andrew
