Apparently, my response from yesterday did not post. Trying again. The code above worked, but once the button changed to red, it stayed that way, no matter what combination of inputs there were. I started wondering if maybe I could just add a third sub, similar to UnwindChart, where the selection of G7 changes the button color the same way F26 does, just with values specific to those cells. The code would then run at each change in either cell, regardless of which is selected first, or later changed. Thoughts?
