Hi Midlidner,

I have a question for you but I incorrectly only sent it to bit4005433864. I would appreciate if you could please take a look at it as well.

Here it is:

Hi.

I have been trying to use this solution you gave as a model for the solution to the Instructions for Lesson 5 Section 15 but I just can’t seem to figure it out. I think I’m confused about the range from 0-50 for the j = 3 section . Every time I try a new code using < 50 or 1…50 I end up in an endless loop.

i = 3
while i > 0 do
print i
i -= 1
end

j = 3
until j == 0 do
print j
j -= 1
end

Now rewrite your `while` loop using `until` . You still want to `print` out the numbers 1 through 50, inclusive.

This is one of my many attempts which is wrong:

j = 3
until j ==0 < 50 do
print j
j -= 1
end

Thanks for any explanation you can give me.
