invoke-webRequest not working

Question

when I go test.htm file I get this

User name: * Required

Password: * Required

Can someone help me please. I send the user name and password via form.fields (see below)

$response = Invoke-WebRequest -Uri 'https://booking.mylab.com/llbooking/' -SessionVariable rb
$form = $response.Forms[0]
$form.Fields.ctl00_MainContent_LoginView1_Login1_UserName='John.Doe'
$form.Fields.ctl00_MainContent_LoginView1_Login1_Password='Test123'
$form.Fields.ctl00_MainContent_LoginView1_Login1_LoginButton='SIGN IN'
$response = Invoke-WebRequest -Uri 'https://booking.mylab.com/llbooking/' -WebSession $rb -Method POST -Body $form.fields
$response.RawContent | out-file test.htm

Since we don't have access to your web site, we won't be able to test your code and fix what's wrong. I don't think that setting LoginButton to 'SIGN IN' is going to do anything, but then again, I don't know how that page works.
