Giveaways are tricky

I have been trying to set-up a giveaway for my new release, Colorado Searing. Seems pretty straight-forward at first glance. It's not. It's tricky. I did get my novel uploaded, I got all the information in (with just a few errors as I learned what the form was asking for), and then got an error message saying the cover was missing and must be there for the giveaway. I uploaded the cover and it said I either had the wrong type of file or the file was too large. I tried again, then again. Failed. Again and again. I know I'll eventually get it figured out. After all, I figured out how to write a novel, how to develop a story, how to make characters lovable (or not), and then how to navigate Kindle Create and the publishing process. It's all a learning curve for me and I thank you for your patience.
