CustomPress Displaying Custom Fields

Hi I cannot display custompress fields

I have created posts with custom fields, and have setup single-my_custom.php and have read many posts here and at wordpress.org however I cannot get the custom fields to show up on the page.

I tried adding php tags as mentioned in some posts here in the loop however nothing shows up on the page (both editing single.php and single-my_custom.php)

thanks in advance
