Need Help For WPQuery WHEREIN Clause

This code is working fine but when I select the only Bathroom Type It’s not working. Please help me so that my multiple search system can be work properly.

$  Bathroom_Type = implode(',', $  _POST['room_type']); $  style_type = implode(',', $  _POST['style_type']);  $  args = array( 'post_type' => 'MyGallery', 'meta_query'=> array( 'relation' => 'AND',         array(             'key' => 'Room',             'value' => $  Bathroom_Type,             'compare' => 'IN',             ),           array(             'key' => 'Style',             'value' => '$  style_type',             'compare' => 'IN',             )             )             );      //Show Result     $  query = new WP_Query($  args);      if ( $  query->have_posts() ) {             while ( $  query->have_posts() ) {                      $  query->the_title();                    echo the_title();           }          }
