Try to use & instead of & in URL-s.

Dear Qnn, Thanks, it exactly the URLs problem, the querystring that passed to another pages requires to encode using server.URLEncode(abc). we use the url encode when the value passing to the next page contains space or and other special character. This is becoz query string only can accept unicode and alphanumeric characters And it should be decode back using server.urlDecode(abc) to on the next page when it request.
