Where/How To Find Name of Attribute Variable

Hello,

I would like to place some of my attribute values directly below the "Availability" (<span><?php echo $text_stock; ?></span> <?php echo $stock; ?></div>) section of the product page.

I have been unable to determine the naming convention for the attributed I HAVE CREATED and how I could call them out on the page so they display just like the "Brand/Product Code/Availability".

Could someone please assist me in understanding how to determine the name of the variable?

Example:
I would like to list the quantity per package right below "Availability". I have created an attribute (which shows up great under Specifications), and have assigned a value.

My attribute is called "Quantity Per Package"

What would the $_______ code be which I should insert to have this displayed on the page?

Thank you in advance for your help!!
