I am so glad you have joined us in our Bible Verse Challenge. As Bridget mentioned, you can make changes on your upload by clicking "Edit Photo". When I was new, I missed that too, because I thought it meant one could only edit the photo, but you are able to edit everything there. I often have to go back and edit mistakes.
If at all possible, it is helpful if you can put the link to your BVC12 creation in your post.
