Directions? What Directions?

Thanks to a GR friend and reading directions I may have a website problem solved.
I started a website because an author is supposed to have one. It grew into a multi-paged affair including a Shop. After all, the Site was supposed to be a way to sell some of my books.
In truth the Site is an end of itself now. In spite of the work and deadlines or maybe because of them, it keeps me engaged and active in marketing my books.
Unfortunately my Shop never worked correctly. I didn't know why and could never seem to track down the reasons.
But a friend wanted a copy of a book. Yes, I could email the pdf but she insisted on arguing with that Shop monster.
First was a problem with the set up so PayPal and the Shop refused to acknowledge each other's existence. That problem turned out to need some help from another friend to find and click on the necessary box.
Then came the problem wherein the Shop insisted a pdf was something I should mail instead of offering a link to the pdf. This was an old problem I had tried unsuccessfully to solve before. The set up page looked correct.
When all else fails, follow directions.
I went back to the basic tutorials about downloads. My pages were set up correctly.
What I had missed was on another page in another location. I had mislabeled the download method.
I love to write. I find marketing frustrating and time consuming. Someday I will learn directions help.
