Buy Now button not working

[Guest]

This site only has one product, no need for catalog pages so I wanted to put button on index page to buy now. I tried to cut and paste info from product_info.php, but apparently still too novice to piece it together myself.

Do I make changes on the includes/languages/english/default.php page to add the buy now button?

 

And can anyone tell me how to script the button to go directly to the shopping cart?

Thanks for the help!
