No need for clumsy code in ZPT 2) your code below returns a list, so all you get is the string representation of a list. Works but does not look so fine ;) -- years = 1 newBal = balance( balance*(rate*years)) You call balance as function by using (). Try your function in the interactive interpreter if unsure, e.g. balance = 5000 rate = 8 # in percent I assume? You should state that in the form years = 4 newbalance = balance * (1+rate/100.0) ** years if you output newbalance, you will see if it does what you want. if you transfer it into the python script, replace the assignments with balance = context.REQUEST.get(balance,0) rate = context.REQUEST.get(rate,0) years = context.REQUEST.get(years,0) and return newbalance at the end. (You can also skip the variable and return the result of the expression directly) I'd point the form to itself and make the output just below it. span tal:content=here/doStuff / thats all. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
