After reading this entire thread I am still unable to make downloadable products work.
I have a single FREE product which is in the form of a PDF file or a Zip file. I have uploaded both to the download directory and I can see both of them in the Download Manager as being valid file names.
I have created an option name called downloads and is type dropdown.
I have two option values one called PDF File, the other called Zip file both of which specify the proper filename to be downloaded.
Everything looks good to me in the admin but when the shopper goes to look at the product, there is no way to download anything nor does the choices for PDF or Zip show up.
The site is located at https://www.clarkemfg.com/cart and the product is the only product in the last category "Factory Seconds" This is a free product.
I am attaching screenshots of my admin screens. Can anyone tell me why this isn't downloadable?
