Short code not working

Hi Friends,

I have a added this shortcode to a child themes functions.php file. But it is simply outputting [current crn] when I put it in a Grid Row in the ALB.

It works fine in the regular editor. Please guide me to the best way to make it work in ALB.

Thanks!

The shortcode is below.

// Add Shortcode
function current_crn() {

	// Code
switch_to_blog (7);
    $args=array(
      'tag' => 'cerp',
      'showposts'=>10,
      'caller_get_posts'=>1
    );
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      echo '10 recent Posts with CCC Tag';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <ul><li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a><p><?php the_post_thumbnail( 'widget', array( 'class' => 'alignleft profile-img' ) ); ?><?php the_excerpt(); ?></p></li></ul>
       <?php
      endwhile;
    } //if ($my_query)
  wp_reset_query();  // Restore global post data stomped by the_post().
  restore_current_blog();	
}
add_shortcode( 'curent crn', 'current_crn' );
