[thelist] validation expression help

[Casey Crookston]

I need to use a Validation Expression to make sure a date is entered
correctly.

ValidationExpression="\d{2}/\d{2}/\d{4}"

That works unless the date is something like 1/1/2004.

ValidationExpression="\d{1}/\d{1}/\d{4}"

That works unless the date is something like 10/10/2004.

How do you build an option into the expression to allow 1 or 2 numbers?

Thanks, Casey
