Error on RAIDStatus

Unfortunately i didn’t get ist to work.
a-team@nagios:/usr/lib/nagios3$ ./check_synology -h shiva
./check_synology: line 29: syntax error near unexpected token `(‘

The line 29 in the script is:
./check_synology: line 29: `OID_RAIDStatus=”1.3.6.1.4.1.6574.3.1.1.1″ usage() {‘
OID_RAIDStatus=”1.3.6.1.4.1.6574.3.1.1.1″ usage() {

It would be nice if anybody can give advise.
