 * Hi Guys,
 * I’m showing a grid of posts with get_posts() function and trying to control category
   parameter value from a custom field.
 * my code only works if category parameter gets value from echo function when I
   do echo value as a number rather than variable for example:
 *     ```
       $args = array( 
       	'numberposts' => 6,
       	'category'         => '<?php echo "25";?>'
               ,);
       ```
   
 * but it doesn’t when I do something like
 *     ```
       $catid = get_field( "id_of_product_category" );
       $args = array( 
       	'numberposts' => 6,
       	'category'         => '<?php echo $catid;?>'
               ,);
       ```
   
 * at the same time I’am able to
 * `echo $catid;`
 * on the page and it does show correct value set in custom field.
 * Why I can’t get it to work to change category parameter then?
