I'm pretty low-level at C++, but decided writing up a program to do some playtesting work for me would save a lot of time. Anyway, I'm almost done - been debugging for a little while, and I've managed to bring it down to 16 repeats of the same two errors...and I get the impression that the illegal breaks are a result of the illegal cases.
I've looked at various help threads throughout the web for these errors, but I still haven't been able to figure it out.

Thanks in advance for any help. I'd keep looking things up rather than make a post, but I really need to get this done soon.

switch needs {} around the cases
e.g.

switch(var)
 {
        case 0:  do stuff;
                      break;
        case 1:  do stuff;
                       break;
}

...And now I feel like an idiot.

Thank you, really! I applied that to my code, had to move a few variables from local to global, and then everything ran smoothly.
Now I can get other things done~

Nah, sometimes it takes fresh eyes, so never a problem.

As an aside, I'd avoid the global variables if at all possible. Declare them in main() and pass them into your methods when needed. I hadn't noticed them before because I was scrolling around to find the switch.

May I ask why you haven't used

if (stuff && stuff) {}

instead of doing

if (stuff)
  {if (stuff2)
}

?
I`m a newbie as well, and I can`t find a reason to use embedded if statements instead of if (&&), since you aren't using else. That`s just what I noticed in the beginning of your code.
