Stock Available.

I am having problems with clicking the box that says Stock Available. It keeps on saying it isn’t selected so I go down and select it, and then it does the same thing over and over again. I have an e-book that I’m trying to sell and it won’t let me do anything about it. FYI – it is in test mode til I get it working and then I will have more ebooks to sell (and hopefully other products too).
