And if I copy/paste the string into a regular expression validator instead of a custom validator, I get the error message that (((0[1-9]|[12][0-9]|3[01])([/])(0[13578]|10|12)([/])(\d{4})) is not a valid regular expression. that happens for all these expressions

This is a dumb question but I'm working on a school project and none of these strings seem to work for me. I just slide a customvalidator onto the screen, set the ControlToValidate to the textbox I want and copy/paste the string into the ClientValidationFunction, right? Anything not in exact format will cause me to get a SQL error. Any help would be greatly appreciated.

It matches: 01/01/0000 01/01/0023 01/01/0123 01/01/1234 which are not a valid dates. :( Maybe you can fix it!

This pattern works in Jscript (IE only) but it doesn't in Javascript (Firefox and other browsers).

It matches 29/02/2003, which is not a valid date.

La idea de esta validación es combinarlo con un popup de tipo calendario. Por eso la expresión es siempre dd/mm/aaaa
