Thanks for this answer.

On my code from my second post, it appears that my calculation of the Dot11High is creating a series that can be plotted, but extracting the values out of the series to use in the IF statement and to assign the Entry is not working. I have tried everything I can think of, like using different offsets in the [], but I can't figure out what I am doing wrong.

Thoughts anyone? This seems like one of those dumb simple problems.
