I also had this issue. Good thing I found this answer before I drove myself crazy.
Thanks for the heads up. Hope to address this soon.

I am posting this issue on behalf of Alan, who emailed me directly. One thing I'm noticing is that he uses '**' to square the standard deviation instead of '^'. This may be the reason for the problem, in which case we just need to add a hint that shows the user how to correctly square something in R:
"I don't seem to be able to get past this question, no matter what method I use to calculate the variance from the standard deviation."
