<!--
/*
This is form validation code. 

Using this code to validate a form will prevent the form from being submitted 
until all of the errors are cleared. 

-----------------------------------------------------------------------------------------
Use these global variables for the "Good" and "Error" styles and 
to display a global error message if any error are found.

NoErrorStyle = "NoErrorStyle";
ErrorStyle = "ErrorStyle";
GlobalErrorDiv = "someGlobalErrorDiv"; (not required)

-----------------------------------------------------------------------------------------
To validate a field set the following properties of the object:
validateType - How the value of the object will be tested.
validatestyleid - The id of the object that should have the error style applied to it.
errordivid - The id of a div object to display when there is an error.

All of these fields are optional, but if you leave off the validatestyleid and errordivid 
no error message will be shown, but the page will not submit.


-----------------------------------------------------------------------------------------
The validation options are (case-insensitive):
    date (not implemented)
    zip
    phone
    notblank
    numeric (not implemented)
    integer
    email
