I needed admin to be able to enter product id for special product to display on home page:
Ex:
http://www.ontoppaintball.com
Yes, I have product id; but I also need product name, thumbnail, price and etc. for this product. Same as bestsellers module works but with only one product with id assigned by store admin.
I get "$specialid" and use it in "special.php" to select all info for this product and store it in "$special".
Now I can use all the info such as "$special.product", "$special.desc" and etc. in templates.
So, adding this variable into templates was not enough. Yes, I could get tumbnail and link to product page, but not product name and price.
