/*

FORM VALIDATION SCRIPT
written by John McGAraghan for inter@ctivate

the document's <form> declaration tag should have an onSubmit parameter as follows:
    onSubmit="return formVal(this, this.emailfield.value);
where "emailfield" is the name of the form input field for an email address
if the second argument is not passed, no validation will be done on email.

Required Select boxes should have a default "--Select One--" field at index 0 and the 
value of that option should be null (i.e. value="").

support for radio, checkbox, and textarea field types is not present at this time.
