I second what Ray said. Although the image of your work that you posted is reasonably neat, many people post images that are blurry or messy or otherwise difficult to read. One of the main problems with work posted in images rather than as text here in the input pane, is that people responding can't insert a comment at the point where an error lies, but instead have to describe the location of the error.

I am closing this thread. Please start a new thread with the problem and work shown directly in your post.
