<p>Here are a couple examples of calling the function:</p>
<h2>Method 1 - just like "classic ASP"</h2>
<p>1 + 2 = <%= Add(1, 2) %></p>
<hr />
<h2>Method 2 - Page_OnLoad</h2>
<p>
<asp:Label id="lblValue1" runat="server" />
 + <asp:Label id="lblValue2" runat="server" />
 = <asp:Label id="lblResult" runat="server" />
</p>
