Editing HTML and I crashed my site

https://www.iluminaraerial.com/

Here’s a link to my site as well as the section of HTML that I messed with:

<div id=”masthead”><!– masthead begin –>

<div id=”top”>
<h1 class=”logo”>/” title=”<?php bloginfo(‘name’);

<div id=”botmenu”>
<?php wp_nav_menu( array( ‘container_id’ => ‘submenu’, ‘theme_location’ => ‘primary’,’menu_class’=>’sfmenu’,’fallback_cb’=> ‘fallbackmenu’ ) ); ?><img src=”https://i685.photobucket.com/albums/vv216/EMaginationEMaging/color-2.png&#8221; border=”0″ alt=” photo color-2.png”/>
</div>

</div><!–end masthead–>

Using ftp or the file manager supplied by your host upload a new copy of your theme to emaginationaerialcom/wp-content/themes/

well I took the code from my theme and put the original header code back in in place of what was there. So now the page opens, but the navigation menu has disappeared.
