Ws2812 code and terminal not working right.

I making a small light for my robot using the ws2812 leds. I modified the code to change lights and patterns which is selected by the ( int h)

The problem is when I try to run terminal code to change (int H)h the led pattern changes but the light wont flash?

Also is there a simpler way to code this?
