This page demonstrates customized error messages that override the standard error messages.
If you want to use your own error message for some datatype - please define variable called
<your_validatorName>Error="your\ error\ message"
For example if you want to define custom error message for zpFormInt you should write the following: <input value="" size="23" name="only_digits" type="text" class='zpFormInt zpFormIntError="Oh!\ This\ is\ not\ digits!"' />
Don't forget to put slashes before spaces in value.
