Tim, Check out qForms: http://www.pengoworks.com/qforms/
While it doesn't have the exact type of validation you're looking for, it'll be very easy to write on. Once written, it'll be completely re-usable from page to page. There are detailed examples of the API at: http://www.pengoworks.com/qForms/docs/examples/index.htm Best of all it's free and it works! -Dan > -----Original Message----- > From: Tim Do [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, September 18, 2002 12:34 PM > To: CF-Talk > Subject: OT: js validation > > Hello all, > > I need a script that will validate a text field which contains units of an > apt complex.
