"Attempt to call a table value" (NumberRange)

I’m not sure why, but when I use a NumberRange it gives me the error “attempt to call a table value”
I just have:

for i in NumberRange(100) do
     -- script
end

That’s not how you create one.

That said, I have no clue if this actually works the way you’re trying to make it work, and numeric for loops are a lot more efficient.
for I = 1, 100 do
