Custom design blog can't change

I just got my blog custom design. Designer asked me where do i need to place the ad and i told him what I wanted. Now I want to add more adds different places, I can't just do it because he need to modify the codes in the template.

I thought I could just add the ads to anywhere I want without any modifying anything.
Can someone clear this up for me...

Is it a WP design? Or HTML/CSS?

Either way its not that hard to add and remove adverts.

The code in the template will have to be modified.

it all there but the designer told me i need to add codes(ad codes) in to sidebar.php and css.
it wordpress

can i paste my codes here so you guys can help or not a good idea

Ya that a good idea .. post your codes here .. so someone can give you effective suggestions ..

this is my sidebar.php

<?php
/**
* The Sidebar containing the main widget area.
*
* @package WordPress
* @subpackage Twenty_Eleven
* @since Twenty Eleven 1.0
*/

$options = twentyeleven_get_theme_options();
$current_layout = $options['theme_layout'];

if ( 'content' != $current_layout ) :
?>
<div class="sideBarTop"></div>
<div class="sideBarMid">
<div class="sideBarMidInner">
<?php dynamic_sidebar( 'sidebar-9' ); ?>
</div>
</div>
<div class="sideBarBottom"></div>

<div class="sideBarTop"></div>
<div class="sideBarMid">
<div class="sideBarMidInner">
<?php dynamic_sidebar( 'sidebar-10' ); ?>
</div>
</div>
<div class="sideBarBottom"></div>


<?php endif; ?>
