Dear All,

I would like to to get the correct total values of correct, wrong answer from the below code.

it is a quiz with Next button and Submit button on last question:

<asp:RadioButton ID="RadioButton1" runat="server" AutoPostBack="True" GroupName="a" OnCheckedChanged="show" />
<asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="True" GroupName="a" OnCheckedChanged="show" />
<asp:RadioButton ID="RadioButton3" runat="server" AutoPostBack="True" GroupName="a" OnCheckedChanged="show" />
<asp:RadioButton ID="RadioButton4" runat="server" AutoPostBack="True" GroupName="a" OnCheckedChanged="show" />

<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Next" />
<asp:Button ID="btnSkip" runat="server" OnClick="btnSkip_Click" Text="Skip" /></td>
<asp:Label ID="lblQuizResult" runat="server" BorderStyle="None" Style="font-weight: 700;"></asp:Label>
<asp:Label ID="lblgoodAnswer" runat="server" BorderStyle="None" Font-Bold="true"></asp:Label>
