                <?php //comments_template( '', true ); ?>
            <?php //endwhile; // end of the loop. ?>

        </div><!-- #content -->
    </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

please tack a look on this also

I tried your code and everything is working fine.
I can see a form on admin side as well as on my template page.
Sorry if I am not getting what you want :(
Can you explain the output you want in short

[AARTI SHRIVAS]

@code_rum
when i am submit my form in fron and side then i get this message

This is somewhat embarrassing, isn’t it?

It seems we can’t find what you’re looking for. Perhaps searching can help.

i don't understand what i am doing wrong in code

[code_rum]

you have not given action in your form.

<form method="post" action="page-you-want-to-redirect-to">

[AARTI SHRIVAS]

i am redirecting on the same page so no need to give action in tag.

[code_rum]

Just change the value of name to anything like name="fname" and it gets solved

<lable>Your name</lable> <input type="text" name="fname"><br/>

May be this will work for you

[AARTI SHRIVAS]

thankyou to reply my problem is solved
