I've successfully added a new field (format) to my Product - Music product type. The new field displays on my product creation pages and is listed in my Admin>Extras drop-down menu. I can edit the list of values for media formats there (LP, CD, DVD, etc.).

The problem I'm having now is getting the information to display on the storefront's product pages. I've edited the tpl_product_music_info_display.php file to match the same way it handles the artist field (which displays on the product pages in the productDetailsList). I've looked at other files handling the artist field to make sure the format field is always handled the same way. But no matter where I look or modify, I can't produce the field output on the product page.

I've looked in my templates and everywhere else that handles music product files (and forum threads that deal with general products doing the same). But can't even find something that alters the existing displayed fields (Model number and Artist) to indicate I'm on the right track. What very fundamental step am I missing to get the information displayed on the store's product pages? Thank you.
