[Zope] Forcing

[Pedro Silva]

Hi,

How can I force a field to just have a value type? Example: the name field
will just receive letters, it can'r receive numbers.
Can anyone tell me how can I do this?

Another thing. Do anyone knows where I can get information about Tiny
Tables? I already searched in www.zope.org, www.egroups.com, and
www.google.com, but I couldn't get anything.

Please send you answers to: psilva@ruido-visual.pt

Thanks,

Pedro
