external page with list of category posts

I am trying to create a simplified version of my blog to be used for cell phones. I have created a simple html file in my root directory called mobile.php that lists the categories. Then you click on one category and it goes to a page that lists those pages sub-categories. Now what I want to do is, when a subcategory is clicked it will go to a page that lists the most recent posts in that subcategory. I can’t seem to figure out how to do this. for the page that lists categories this is what I have:

?php query_posts(‘category_name=canton-monday’); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<?php if ( in_category(‘canton-monday’) ) { ?>
<div class=”post-cat-three”>
<?php } else { ?>
<div class=”post”>
<?php } ?>

<!– Display the Title as a link to the Post’s permalink. –>
<h2>“><?php the_title(); ?></h2>

<!– Display the Time. –>
<small><?php the_time(‘F jS, Y’); ?></small>

<!– Display the Post’s Content in a div box. –>
<div class=”entry”>
<?php the_content(); ?>
</div>

<!– Display a comma separated list of the Post’s Categories. –>
<p class=”postmetadata”>Posted in <?php the_category(‘, ‘); ?>
</div> <!– closes the first div box –>

<!– Stop The Loop (but note the “else:” – see next line). –>
<?php endwhile; else: ?>

<!– The very first “if” tested to see if there were any Posts to –>
<!– display. This “else” part tells what do if there weren’t any. –>
Sorry, no posts matched your criteria.

<!– REALLY stop The Loop. –>
<?php endif; ?>

I want to list the posts in the canton-monday category. But ti is not working. It just shows a blank page and no error message. Can someone send in in the right direction for calling the blog information from the root directory and then listing a simplified version of the posts(no stylesheets)?
