Querying multiple custom fields

I’m having some trouble querying multiple custom fields. I have created a custom search form that the values are posted to the query. It’s working, but it’s only querying the 1 value. Here is the code:

<?php
	$bedrooms = $_GET['bedrooms'];
	$bathrooms = $_GET['bathrooms'];
	$bedroom_key = 'bedrooms';
	$bathroom_key = 'bedrooms'
?>
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts( array(
	'post_type' => 'property',
	'posts_per_page' => '2',
	'paged' => $paged,
	'meta_query' => array(
		array(
			'key' => $bedroom_key,
			'value' => $bedrooms,
			'compare' => '>='
			),
		array(
			'key' => $bathroom_key,
			'value' => $bathrooms,
			'compare' => '>='
			)
			)
			) );?>

So really, this query is only getting the posts that match the “bedrooms” but not the “bathrooms”. This is live at http://www.bayofplenty.info
