Works if you fix the mistake in the code

The Installation tab of this plugin says to use the following code to display the information from your meta field:

if (function_exists('wp_get_terms_meta'))
{ 

  $MetaValue = wp_get_terms_meta($category_id, $meta_key ,true); 
 //where $category_id is 'category/term id' and $meta_key is 'meta key'
} 

//meta value for meta key $meta_key
echo $metaValue; 

but he misspelled the variable for the echo. It’s supposed to be $MetaValue, not $metaValue. It’s suppose to have a capital M. With that fix it will display properly.
