Dynamic update of rate-limit

Hello, To update users rate-limits dynamically i have defined following custom attributes in dictionary file ATTRIBUTE       Subscriber-NAS-Vendor      3050        string ATTRIBUTE       Subscriber-Total-Bytes        3051        integer64 ATTRIBUTE       Subscriber-Quota                3052        integer64 ATTRIBUTE       Fair-Usage-Rate                 3053        integer and written following unlang codes in accounting section:         #  Rate Policy for unlimited, fair usage and limeted accounts         update control {                 Subscriber-NAS-Vendor = "%{sql: SELECT nas_vendor FROM radcheck WHERE username='%{User-Name}' AND attribute = 'Cleartext-Password' limit 1}"                 Subscriber-Quota = "%{sql:SELECT IFNULL(quota, 0) FROM radcheck WHERE username='%{User-Name}' AND attribute = 'Cleartext-Password' limit 1}"         }         if (&control:Subscriber-Quota > 0) {                 update control {                         Subscriber-Total-Bytes = "%{sql:SELECT IFNULL(SUM(IFNULL(acctinputoctets, 0) + IFNULL(acctoutputoctets, 0)), 0) FROM radacct WHERE username='%{User-Name}'AND acctstarttime\                                 >= DATE_SUB(LAST_DAY(NOW()), INTERVAL DAY(LAST_DAY(NOW()))-1 DAY)}"                         Fair-Usage-Rate = "%{sql:SELECT IFNULL(fairusage_rate, 0) FROM radcheck WHERE username='%{User-Name}' AND attribute = 'Cleartext-Password' limit 1}"                 }         }         #  over qouta fair usage acoount         if (&control:Subscriber-Quota > 0 && &control:Fair-Usage-Rate > 0 && &control:Subscriber-Total-Bytes > &control:Subscriber-Quota) {                 switch "%{&control:Subscriber-NAS-Vendor}" {                         case "Mikrotik" {                                 update reply {                                         &Mikrotik-Rate-Limit = "%{sql:SELECT GetRate('%{User-Name}', 'fairusage')}"                                 }                         }                         case "Cisco" {                                  update reply {                                         &Cisco-Avpair = "%{sql:SELECT GetRate('%{User-Name}', 'fairusage')}"                                         &Cisco-Avpair += "%{sql:SELECT GetRate('%{User-Name}', 'upload')}"                                 }                         }                 }         }         #  over quota limited account         elsif (&control:Subscriber-Quota > 0 && &control:Fair-Usage-Rate == 0 && &control:Subscriber-Total-Bytes > &control:Subscriber-Quota) {                 update disconnect {                         &User-Name := "%{User-Name}"                 }         }         #  unlimited and other accounts under quota         else {                 switch "%{&control:Subscriber-NAS-Vendor}" {                         case "Mikrotik" {                                 update reply {                                         #

But if i set Mikrotik-Rate-Limit = "2048k/16324k" in radreply table atleast upload rate is obeyed. Do i update reply in wrong place, or doing some other things wrong? Thanks.
