I don't believe the templating system supports that. You can express the sum of two variables that you passed to a template but you can't create set the sum of two variables inside a template; i.e. You can do this: <html>$(x+y)</html> You can't do this: $z = x+y <html>$z</html> I believe this is because the templating system specifically chooses not to support the assignment operator (AFAICT). Also, it seems to me that the convention is to compute the values outside of the template system and then pass them as arguments to the template system, whose job should only be to display the values. -- John -- You received this message because you are subscribed to the Google Groups "web.py" group.
