Can't get a true "full width" page using Gallery template

I’m using the Gallery theme (parent: Thematic) for my site and although the theme has a page template called “Full Width” that page template only removes the widgets but doesn’t actually push the page over to claim the spot held by the sidebar.

Can anybody help me??? Everything else about my site is just how I want it, but this is driving me INsane!

I read some instructions here…

https://www.ads-software.com/support/topic/full-width-page-creating-your-own-page-templates

…but there was no page.php file for the child theme and when I tried applying the rules to the parent theme, I found there was no line that said <div id=”left-column”>.

Here’s the entire Thematic page.php file if it will help!

<?php

// calling the header.php
get_header();

// action hook for placing content above #container
thematic_abovecontainer();

?>

<div id=”container”>

<?php thematic_abovecontent(); ?>

<div id=”content”>

<?php

// calling the widget area ‘page-top’
get_sidebar(‘page-top’);

the_post();

thematic_abovepost();

?>

<div id=”post-<?php the_ID();
echo ‘” ‘;
if (!(THEMATIC_COMPATIBLE_POST_CLASS)) {
post_class();
echo ‘>’;
} else {
echo ‘class=”‘;
thematic_post_class();
echo ‘”>’;
}

// creating the post header
thematic_postheader();

?>

<div class=”entry-content”>

<?php

the_content();

wp_link_pages(“\t\t\t\t\t<div class=’page-link’>”.__(‘Pages: ‘, ‘thematic’), “</div>\n”, ‘number’);

edit_post_link(__(‘Edit’, ‘thematic’),'<span class=”edit-link”>’,'</span>’) ?>

</div><!– .entry-content –>
</div><!– #post –>

<?php

thematic_belowpost();

// calling the comments template
if (THEMATIC_COMPATIBLE_COMMENT_HANDLING) {
if ( get_post_custom_values(‘comments’) ) {
// Add a key/value of “comments” to enable comments on pages!
thematic_comments_template();
}
} else {
thematic_comments_template();
}

// calling the widget area ‘page-bottom’
get_sidebar(‘page-bottom’);

?>

</div><!– #content –>

<?php thematic_belowcontent(); ?>

</div><!– #container –>

<?php

// action hook for placing content below #container
thematic_belowcontainer();

// calling the standard sidebar
thematic_sidebar();

// calling footer.php
get_footer();

?>

Thanks a million in advance if anyone can help me fix this!!
