In my experience, this is almost always the sign of a missing "end". If I add one to the bottom of your code, if does indeed go away. I can't see where exactly it's missing though. Try cleaning up your indentation, then it should be obvious.

Hi -

For starters, you're gonna want to replace "else if" with "elsif". The "else if" starts a second if, so using "else if" will leave you one "end" short. That'll get you a syntax error for sure.

This should be:

elsif num == 0

I haven't looked at the rest of the syntax, though, but I hope that
helps.

That doesnt appear when i try to execute... there is no \255 character
where it says there is one. Maybe it's because you're copying off of the
MB?
