webbot validation customization

Hello,

I created a basic contact form in FrontPage 2003 with a validation field to combat spamming.  
There is a graphic that displays "1234" and an input box that asks the user to fill in the numbers that appear on the graphic.  This input box has a value set to the same "1234".  When I test out the validation, if the code is not input correctly, I get this message:  "please enter a value equal to "1234" in the text field.".  

Is there any way to customize that message so it does not display the "1234" value, but instead says something like "incorrect value in the text field" instead?  The code for part of the form is attached below.
Thanks.Start Free Trial
