 FormValidation Script v1.50
 Copyright © Curtis Sund (curtis@igz.net)
 Provides an array with form elements and the type of validation each
 individual one needs.  Does the needed checking.

 Below is the attached javascript file that contains all of the 
 functions called that do the dirty work.  Here is the code that goes 
 in the header of the page:

 <script language="Javascript" src="../javascript/formvalidation.js"></script>
 <script language="Javascript">
   oFields = new Array()
   oFields[0] = new Array("txtFirstName", "first name", "check", "char", "", "", "20", "")
   oFields[1] = new Array("txtMiddlename", "middle name", "nocheck", "char", "", "", "20", "")
   oFields[2] = new Array("txtLastName", "last name", "check", "char", "", "", "20", "")
   oFields[3] = new Array("txtSSN", "social security number", "check", "ssn", "", "", "9", "")
   oFields[4] = new Array("txtPhoneNo", "phone number", "check", "tel", "", "", "", "")
   oFields[5] = new Array("txtAssociateId", "associate id", "nocheck", "common", "", "", "", "")
   oFields[6] = new Array("cboGroupId", "group id", "nocheck", "num", "", "", "", "")
   oFields[7] = new Array("txtAdminPassword", "password", "nocheck", "password", "", "txtVerifyAdminPassword", "", "")
   oFields[8] = new Array("txtVerifyAdminPassword", "retype password", "nocheck", "password", "", "", "", "") 
   oFields[9] = new Array("txtMonth", "month", "check", "num", "month", "", "", "") 
   oFields[10] = new Array("txtDay", "day", "check", "num", "day", "", "", "") 
   oFields[11] = new Array("txtYear", "year", "check", "num", "year", "", "", "") 
 </script>

 oFields[manually incremented #]

 1st Element - Form field name
 2nd Element - User friendly name for this field -- this is used when 
               alerting an error
 3rd Element - Boolean -- check or nocheck -- Determines whether this 
               form field needs to be filled out
 4th Element - Type of data to check for.  The possible types are: num, 
               common, char, password, email, ssn, zip, tel, date
 5th Element - Type of data to check for if it's a date field.  See 
               the examples above for array numbers 13-15.  The actual 
               value will be numeric so we enter num for the 4th 
               element but then we want to make sure that the number 
               they are entering half way resembles a year and isn't 
               simply 9999.  That's what this field does in the array.
 6th Element - Verify password field. This is the verify password field 
               that needs to match the password field.
 7th Element - Specific length of characters for this field. 
 8th Element - Maximum length of characters for this field.
               
 The form needs to call the main function I've created within the JS 
 file like this:
 
 <form NAME="frmQueryUser" ACTION="user.asp" METHOD="post" onSubmit="return checkData(this)">
 </form>
