Plinko simulator!

rantiv (101)
Just a heads up, I'm going to be needing a lot of help! So we are making a program that simulates plinko. There is just a lof of styling that is making it a little difficult for me. Also we are doing it through an online textbook that is really picky and my numbers for the simulation arent the same one it should be. This is what i got...

should look like this

Ok, I've ran the code.

There is one thing that I found weird and hard to navigate:
Why is it i get the intro and yet there is no prompt to tell me what to input I type any number and then it goes on and tells me my options but it runs as if I already selected my option. The weirdest part of that is it happens every single time.

Maybe a do {...} while (...) would fix it?

Other then that I haven't the slightest clue.

For instance this is my output:

I hope that helps at least a little.
