CustomValidator control not executing handler

[ken bus]

I've done everything to get it to validate but no luck:

HTML:

<asp:TextBox id="TextBox1" style="Z-INDEX: 152; LEFT: 39px; POSITION: absolute; TOP: 68px" runat="server"></asp:TextBox>

<asp:CustomValidator id="CustomValidator1" style="Z-INDEX: 153; LEFT: 201px; POSITION: absolute; TOP: 74px" runat="server" OnServerValidate="Test" ErrorMessage="CustomValidator Test" ControlToValidate="TextBox1"></asp:CustomValidator>

<script language="vb" runat="server">
Sub Test(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
args.IsValid = False
TextBox1.text="Test"
End Sub
</script>

I've used code behind but it doesn't work either.
What am I doing wrong? Am having no trouble with the other validators.

It doesn't look like you've set the ClientValidationFunction property (which
is the name of the client side function that will run to validate the
control you've marked with the ControlToValidate property) and you don't
have a client-side function written either.
