CustomValidator doesn't validate on a textbox that is empty

[Ned]

I am trying to use a CustomValidator on a textbox. The Validator uses
a client-side funtion but it doesn't run if the textbox is empty. If
there is data in the text box it runs fine. Any suggestions
appreciated. Thanks!

Required Field Validator?

Also, are you saying it doesn't run or it passes validation?

If you wish to validate the fact that it is empty you need to use a required
field validator.
