Rick, All of your images came through, however they were not stacked as I think you were trying to do. In stead they were all lined up. So the red line representing 3910 is actually at the end of the text, followed by a red arrow pointing at the text followed on the next line by a red oval which is next to the original image. You may want to put those in an image program and merge them all together for full effect.
Just a suggestion.
