The sheet worked flawless in an older SMath version, but the most recent SMath-incarnations result in problems: the error seems to originate with the summation command. How do I get this program working again? I attach the original files: thanks for any feedback! Kind regards from a Belgian SMath-fan, Jan Original file with summation error.sm (144kb) downloaded 22 time(s). Original file working.pdf (191kb) downloaded 27 time(s).

This is because of using "i" as a variable. Currently we have some issues regarding it. Will be addressed soon. Simple change to fix your worksheet: Best regards.
