When I try to create a custom donation button, in the "Your customer's view" window, nothing changes. Even after I save it, nothing changes. It just show the gray window with the X'd out block. I haven't tried to put it on a website yet, because I'm unsure if it'll even work. Is there a reason it's not appearing the "Your customer's view" box? I've tried resizing, and changing the file type between JPEG and PNG, and it doesn't seem to change.
