If the user input is the value of a field in a form that was submitted, just refer to the name of the form field: You can use the special form name syntax to have Zope cast the field value into the appropriate type: . There's a howto on the various possabilities for what goes after the ':'. --RDM ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] R: [Zope] range with variables

The problem is that in both cases the `startindex' is a string, you have tu convert it to int. ATENTION: If 'startindex' is not a valid number the `atoi' method will rise an exception like: Error Type: ValueError Eror value: invalid literal for atoi(): So is better to check first, something like: Error message - INVALID NUMBER Other way is to force `startindex' to be a int like: ... But you could have problems, an exception like above could occur (if someone will input an invalid number) and you can not do something. That's the story.
