Quick PHP Question

Hey.

I’m using a query to show the latest post in the “Featured” category by using this code:

<?php if (! is_paged()):
	$my_query = new WP_Query('category_name=Featured&showposts=1');
	$wp_query->in_the_loop = true;
	while ($my_query->have_posts()) : $my_query->the_post();
	$do_not_duplicate = $post->ID;
?>

Thing is, I want the user to be able to choose which category they want to be their “Featured” category. I have a variable (via Theme Options) with the correct category, thing is, I don’t know how to pass this variable into the query above, particularly this line right here:

$my_query = new WP_Query('category_name=Featured&showposts=1');

I can’t put a variable in there because it’s surrounded with ‘ ‘. IF I remove the ‘ ‘, I get an error.

Any ideas?

Thanks.
