Looping with until exercise had me going


After a few tries, I got the below to work:
i = 1
until i == 51 do
print i
i += 1


Mine rejects that as an answer even though it prints out 1 to 50. It accepts
until j <= 50 do
print j
j += 1
Which makes no sense to me logically. To me this says "Print j until it is less than or equal to 50" ??? Heeeelllpp meee understand
