[Plugin: Peter's Post Notes] Custom Post Types

Hey I tried to add the notes section for custom post types and I can’t get it to work

I tried adding the below where you said and nothing appears

$ppn_post_types[] = 'batterymanufacturing';

im guessing that is what it should be…when clicking on the full list of posts I see

/edit.php?post_type=batterymanufacturing

Thanks allot
