What could be the reason behind the malfunction of this code that was intended to update a label upon input of a specific text value

My JavaScript code is not displaying the text as expected when a certain number is entered on my ASP.NET website. Here is the relevant code snippet:


        <div class="fltlft">
            <%--<asp:TextBox ID="txtCreditPoint" runat="server" AutoCompleteType="Disabled"></asp:TextBox>--%>
            <asp:TextBox ID="txtCreditPoint" runat="server" AutoPostBack="false" AutoCompleteType="Disabled"></asp:TextBox>
            <asp:RequiredFieldValidator ID="rfvCreditPoint" runat="server" ControlToValidate="txtCreditPoint"
                ErrorMessage="Point is required." Text="*" ForeColor="Red" ToolTip="Point is required"></asp:RequiredFieldValidator>
            <asp:RangeValidator ID="rvCreditPoint" runat="server" ControlToValidate="txtCreditPoint"
                ErrorMessage="Point is not valid. Must be 1-10" ForeColor="Red" Text="*"
                MinimumValue="1" MaximumValue="10" Type="Integer"></asp:RangeValidator> 
            <a href="point_value.html" onclick="window.open('point_value.html', 'newwindow', 'width=300, height=125'); return false;" style="font-size: 16px">?</a>
            <br />
            <asp:Literal ID="ltrRecomendedPoin" runat="server"></asp:Literal>
            <br />
            <asp:Label ID="lblUSDValue" Text="" runat="server" ></asp:Label>
        </div>

        <script>
            $(document).ready(function () {
                $('<%= txtCreditPoint.ClientID %>').change(function () {
                    if ($('<%= txtCreditPoint.ClientID %>').val() == "1") {
                        $('<%= lblUSDValue.ClientID %>').text("You are valuing this game at a range of $1.00 to $5.00");
                    }
                });
            });
        </script>

There appears to be an issue with the way you are referencing id's in your jQuery code. Make sure to include a # symbol before all of your references.

For example:

$('<%= txtCreditPoint.ClientID %>').val()

should actually be

$('#<%= txtCreditPoint.ClientID %>').val()
