Answer 1

It seems that your code runs into an infinite loop when asking for the first and second x y z coordinates. Firstly, I'm a little confused as to why you need two different x y and z values; Please correct me if there's something I don't see/understand here, but I believe there would only need to be 1 set of coordinates for the code to function. In case you DO need two separate values/checks for coordinates though, try making them separate variables (example: have the first check be for variables called "x1", "y1", and "z1", and the second check likewise, but with a 2 instead of a 1). I haven't looked too much into the code yet, but I can later. If you could clarify a bit more what each piece of does, that'd really help out as well!
