Unknown Error with Random Stat Assigner

[FC8]

randint(1, 100) generates random numbers in a range starting with 1 and ending with 100.
range(1, 100) starts at 1 but ends at 99.

You don't bump up any attribute if statpoint == 100.

Thank you, so what should I do? I kind of just learned python through guides and stuff. I changed

if statpoint in range(81, 100):
        SPD = SPD + 1

to

if statpoint in range(81, 101):
        SPD = SPD + 1

and tried changing

if statpoint in range(1, 20):
        HP = HP + 1

to

if statpoint in range(0, 20):
        HP = HP + 1

but changed it back.
