I have reformatted your code because the html tags did not display on screen.
Line 183:
Line 184: <table><tbody><tr>
Line 185: <td> <asp:Button ID="Button4" runat="server" Text="LOG-IN" /> </td>
Line 186:<td> <asp:Button ID="Button5" runat="server" Text="EXIT" /> </td>
Line 187:</tr></tbody></table>
If your code is really like that, you should start by replacing the
< and
> by
< and
>
