LOL...I was just really tired. As you said, the mid_line is just fine in the programming. I just forgot to click the little box to plot it :) When my brain is fried it is time to step away ....
The only thing I don't like about what I coded is that a new study has to be made for each color; but, that's not really a big deal...just change one word. I tried to code it so one could just pick the color in the Study with a drop down box but, the cloud formula does not blend well with this concept. It is about choosing between the difference of two variables and then plotting the cloud but, trying to give it a choice on the color just didn't seem to fit easily into the formula so, after a bunch of attempts I bailed. It is not anything I am going to spend any more time on now because what I have works so moving on to other things. Maybe in the future after I learn more, the answer will be apparent and then I'll go back and change it.
