What is wrong with this SYNTAX?

[Alex Katebi]

It is complaining about near STRCMP.

  CREATE TRIGGER bgp.tglobal BEFORE UPDATE on bgp.global
  FOR EACH ROW BEGIN
  IF STRCMP(NEW.Variable_name,'ASN') != 0 THEN
     set NEW.Variable_name=NULL;
  ELSEIF STRCMP(NEW.Variable_name, 'RouterId') != 0 THEN
     set NEW.Variable_name=NULL
  ELSEIF STRCMP(NEW.Variable_name, 'ASN') != 0 THEN
     set NEW.Value=CONVERT(CONVERT(NEW.Value, UNSIGNED), CHAR);
  ELSEIF STRCMP(NEW.Variable_name, 'RouterId') != 0 THEN
     set NEW.Value=INET_NTOA(INET_ATON(NEW.Value));
  ENDIF
  END

Thanks in advance!
