Help a newbie install a piece of javascript with product vars on a product page

[jhkaplan]

In tpl_product_info_display.php, the variable that holds the product's model number is $products_model. The brand would be $manufacturers_name.
There will be different variable names for these in some other pages like product listing, and some pages would not have the information readily available (if the page does not handle products).

Perfect, exactly what i was looking for. Is there a list anywhere of all the product page variables? The ones I need are:
Brand (check)
Part Number (check)
Product Name
Product Sale Price
Condition

Not all are required, but they'd be nice to have.

Thank you again for your help gjh!
