You should really refer to the training resources at the top of this forum. You need to have a better understanding of how dataflow works. You have multiple stop buttons, loops within loops, wait times inside sequence structures that make no sense because they're in parallel to other code with different waits in the same loop. Your stop buttons don't work because when you press one the other one also has to be pressed (the third one is not wired into anything. Perhaps with some description of what you want to do with this code (it's hard to figure out now) someone could help direct you to ways to reformat the code to do what you want (including having a single stop button that works).
