I'm trying to to save syslog and saving logs with a specific hostname based on the IP address. I'm using a if statement and a vaiable to define the file path I want to use. unfortunately I'm getting the folloging error message: nxlog.conf:32; couldn't parse statement at line 36, character 9 in C:\Program Files\nxlog\conf\nxlog.conf; function 'create_var()' does not exist or takes different arguments. 

My conf file is below. Any hint?

    }
    else
    {
        create_var('logPath', $MessageSourceAddress+'/Syslog-'+ strftime(now(), '%Y-%m-%d-%H') + '.log')
    }
