Ok, forgive me if this is something basic. I have the stuff below. It works. What I don't like is that if I enter a value that matches both conditions it displays both error messages. Personally, in that situation, I would rather it just display the first one. How could I go about making that happen?

Thanks,

<%-- This stuff is displayed for user interaction --%>
Go to page: <asp:TextBox Runat="server" name="txtPage" ID="txtPage" Width="50" /> <asp:Button Runat=server ID="btnGo" Name="btnGo" Text="Go" /> Page <asp:Label ID="lblCurrentPage" Runat=server /> of <asp:Label ID="lblTotal" Runat=server /> <br>

<%-- Here are the validators --%>
<asp:CompareValidator runat="server" id="compPrimeNumber"
    Operator="DataTypeCheck" Type="Integer"
    Display="Dynamic" ControlToValidate="txtPage"
    ErrorMessage = "You must enter an integer value." />

<asp:CompareValidator runat="server" id="compPrimeNumberPositive"
    Operator="GreaterThan" Type="Integer"
    Display="Dynamic" ValueToCompare="0"
    ControlToValidate="txtPage"
    ErrorMessage = "You must enter a value greater than zero." />

If this is all happening on the server side, you should be able to disable the second validator if the first is not valid.

In your page_load() do something like this:
