Number printer, Random integer not working

Alright, So I'm trying to create a program on repl.it that prints either even, odd, consecutive or random numbers In which you can decide the time it takes, The amount to print and (for random) the highest and lowest number.

However, whenever I select random and try to run it. This pops up

  File "main.py", line 76, in <module>
    massprint()
  File "main.py", line 24, in massprint
    print(random.randint(int(randhighcap),int(randlowcap)),flush=True, end=" ")
  File "/usr/lib/python3.8/random.py", line 248, in randint
    return self.randrange(a, b+1)
  File "/usr/lib/python3.8/random.py", line 226, in randrange
    raise ValueError("empty range for randrange() (%d, %d, %d)" % (istart, istop, width))
ValueError: empty range for randrange() (100, 1, -99)

Here's the link to the repl project so you can see the code. (Or alternatively the code is below.)
