Why can't I calculate in the file "Nikolai roots.sm"? Clicking the "Recalculate page" button gives the error "F() - function isn't defined.". Is this a problem in different versions of the program or a problem in another?

Possibly, your Smath installation is defective ? Possibly, your Smath version is kaput ? On that last point, Designers can confirm. I will make a PDF, so you will be able to code/sanity. Cheers ... Jean.
