This should be what is needed for all usergroups to show it.... edit the first array for primary usergroup numbers, and the second array for secondary usergroup numbers.
Code:
<if condition="in_array($post['usergroupid'], array(5,6,7,12,14)) OR in_array($post['membergroupids'], array(15,16,17,19)) AND $post[fieldX]" >
Just replace your current "if condition" array with this one, edit the usergroup numbers and the field number, and let me know how it works.
