asp:RangeValidator not working

I'm having trouble with the following asp:RangeValidator control that if I enter a number where the first two or three digits are in between the range it ignores the last digits and still validates.

the range is 1801 - 2201 but all of these numbers still validate:
19, 20, 21, 212, 202, 190, etc.

The test page is here: http://www.glowfishtw.com/stlukes/alumni.aspx
and the code:

<asp:TextBox ID="txtClass" Width="80px" runat="server"></asp:TextBox>
<asp:RangeValidator ID="RangeValidator1" runat="server" ErrorMessage="Enter a valid year." ControlToValidate="txtClass" MaximumValue="2201" MinimumValue="1801" SetFocusOnError="True"></asp:RangeValidator>

How do I get it to only validate numbers between 1801 and 2201?

Thanks

Your problem probably is because the Maximum and Minimum values are STRINGS (by default) ("2201" and "1801")  and not Numbers.

make this change:

<asp:RangeValidator ID="RangeValidator1" runat="server" ErrorMessage="Enter a valid year." ControlToValidate="txtClass" MaximumValue="2201" MinimumValue="1801" SetFocusOnError="True" Type="Integer" ></asp:RangeValidator>

As @Arthur_Wood mentioned, you need to add Type="Integer". Also, add a RequiredFieldValidator also, otherwise the blank values will be accepted.
