When I type purge(k,n) and then press ENTER, my physical Prime says:

["No such variable k" "No such variable n"]

(But Virtual Prime also says that too.)

When I try the sum_riemann again on my physical Prime, I get the same Error: Bad Argument. So "purge" does nothing to resolve the problem.

How about the "restart" CAS command?

I tried to reproduce the problem on my Prime (same software and hardware version as yours), but failed to do so.
