CL Help! Why isn't this graphing correctly?

Can anyone tell me why the last 4 graphs do not graph correctly when the button is pushed?

This is a lot to take in. I’m guessing referring every slide to the first graph is for the timers, but it’s hard to follow.

When I try it, it looks like it keeps graphing the reflection (all the intercepts are opposite) and I’m not getting positive feedback for the y-intercept (maybe something wrong with the lead coefficient by the graph).
Like this:

Are your P-variables supposed to be uppercase or lowercase? You have them lower and upper on the graph and upper in the CL code.
