anyone of out there brighter me in area? =)

begin {    recvdsize = 0    starttime = 400    stoptime = 0 }  {          event = $1          time = $265.01          node_id = $29          pkt_size = $8          level = $4    if (level == "agt" && event == "s" && pkt_size >= 512) { if (time < starttime) {          starttime = time          }    }     if (level == "agt" && event == "r" && pkt_size >= 512) {    if (time > stoptime) {          stoptime = time          }       hdr_size = pkt_size % 512    pkt_size -= hdr_size      recvdsize += pkt_size    }    }    end {    printf("average throughput[kbps] = %.2f\t\t starttime=%.2f\tstoptime=%.2f\n",(recvdsize/(stoptime-starttime))*(8/1000),starttime,stoptime)

}

didn't error message tell line number? anyway, i'd take close @ line contains

time = $265.01
