Click link in Internet Explorer

I've got a macro that I can use to log in to a website and authenticate myself, now I just need to add a section to click a button (which will download a .csv for me).

Here's the login code:

Sub WebLogin()

Set IE = CreateObject("InternetExplorer.Application")
With IE
    .Visible = True
    .Navigate "www.MYSITE.com"
    Do Until .ReadyState = 4
        DoEvents
    Loop
    .document.all.Item("edit-name").Value = "MY EMAIL"
    .document.all.Item("edit-pass").Value = "MY PASSWORD"
    .document.forms(0).submit


    Do While IE.Busy
    Application.Wait DateAdd("s", 1, Now)
    Loop

  End With

End Sub

So, that works fine. Once I'm logged in, here's the info for the button I'm trying to press:

<input name="_qf_GPDetail_submit_csv" value="Export to CSV" type="submit"  id="_qf_GPDetail_submit_csv" class="form-submit">

If anyone could help me out with a bit of code to click this, that'd be amazing!
