'* version [1.5] 10/02/2006 16:49 BAJ - Increasing UIV_MAXLENGTH_ADDRESS
'* version [1.6] 12/04/2007 12:47 SHS - 07-4438 Desc: Input validation for XSS weakness. The problem was occuring due to "<" ">" going into the data.
'* Its require to validate all the hidden and text fields for the brackets. There is already check on the the form fields which checks for all the
