  Not quite yet.
  This is the scenario:

  I have a form which asks the user for one or more category ID's separated by comma. Thus the user will enter 1,2,3 without quotes. The value is stored in a variable called $usercategories
  If I use
  <?php wp_list_categories('include='.$usercategories.'&title_li=' ); ?>
  It works fine, I'll get a list of only those categories. However when I try to use the variable in my single.php

  if (in_category (array($usercategories) ) { ...my loop... }
  it does not recognize the variable, I try to manually enter the value just to check and it works.

  if (in_category (array(1,2,3) ) { ...my loop... }

  if I echo the variable it outputs the list too eg 1,2,3

  I just don't understand why the variable it's not working when used as a parameter for a function. Any ideas?
