I am relatively new to programming in Mathematica (so please excuse my novice code) and am having trouble displaying the updated values of my constants c1, c2, ... , c8 which are displaying to the right if my controls for v1, v2, ... , v8. So as I move the sliders for a1, a2, ... , a8, the values of c1, c2, ... , c8 should be updating.
Also, if you can identify which part of my code is causing the program to run so slowly, that would be appreciated. As I move the sliders, there is a delay in the update of the bar charts.
