Hello there
Can somebody help me with this.
I have a form where the user enters his date of birth from 2 drop downs and a textbox. Month and date are dropdowns and year is to be entered in a text box.

Now if I want to check if the user is not selecting an improper date value like Feb 30th 1900 or April 31st 1999, how can I achieve that.
any help would be appreciated.

Thank you..
