Use this dialog box to create, copy, edit, or delete validators. All the validators stored in the forms database are listed. Validators are a type of global object that defines specific conditions for determining whether input to a component is valid. For example, you could create a validator to check that a user enters values between 100 and 200. Besides checking for valid input, validators can be used to output other data to the form. You can create and attach error messages to a validator.
To create a validator, click New.
To copy, edit, or delete a validator, select the one you want in the list. Then click the appropriate button.
