FORM FIELD VALIDATION
This is a fairly simple process - it will insert a basic Javascript version of Form Field Validation. Only two types of validation are included in this version - Empty Field validation (it makes sure something is there before it lets the form submit) and Valid Email Validation (makes sure a valid email address is in the box). For this, you must have the word 'email' in the form field name itself.
Just highlight the form tag - then go to the Insert Pull-down menu - Insert/Forms/Form Field Validation. All the rest is done for you....
There is a Javascript that is added between you HEAD tags, and the other needed scripting is put into the form in the necessary places.
