/* Edited by Mit (mit@w3systems.net) 19/10/2010

- Remove keyup detection as not necessary.  
- Changed '&' to '&&' in onsubmit if statement (syntax was wrong) 
- Added var for mobile number, and onblur call to function
- Changed if statement in validateContactNumber to validate number of 11 characters (ignoring spaces)
- Added validateMobileNumber function... duplicated actions of validateContactNumber, but will also return true if zero length
