// Javascript form validation routines.
// Author: Stephen Poley
//
// Simple routines to quickly pick up obvious typos.
// All validation routines return true if executed by an older browser:
// in this case validation must be left to the server.
//
// Update Jun 2005: discovered that reason IE wasn't setting focus was
// due to an IE timing bug. Added 0.1 sec delay to fix.
//
// Update Oct 2005: minor tidy-up: unused parameter removed
//
// Update Jun 2006: minor improvements to variable names and layout
//
//
// Altered February 2007 by Ben Huddleston to include additional tags
// changes:
// Added validateInput function for alpha content only
// Changed field css class 'error' to 'good' for valid content so i could 
// assign different looks to the document based on input
// ----------------------------------------------------------------------
