I found this 2000 line script that validates every imaginable piece of textbox form data it can check tons of inputs from social security numbers and dates to credit cards and emails. I think it was written by netscape and it appears to be backwards compatible to NN 2 and IE 3. It checks for the validity of the data then returns a boolean true or false, you can decide for yourself what to do with the return. Any way here is the script. If anyone needs help working it i can help. I hope this is not old news, if so i apologize.<BR><BR>the script:<BR>view-source:http://developer.netscape.com/docs/examples/javascript/formval/FormChek.js<BR><BR>the dev page:<BR>http://developer.netscape.com/docs/examples/javascript/formval/overview.html
