[Solved] Could someone that knows awk good fix this script for me?

Question

I found this script on the linuxquestions site that tests and displays network bandwidth.  There's an error in the script though and my awk experience isn't enough to debug it and is giving me the error:
awk: cmd. line:10: printf ("%4.0f", Ratio)}
awk: cmd. line:10: ^ syntax error
awk: cmd. line:10: printf ("%4.0f", Ratio)}
awk: cmd. line:10: ^ syntax error
^C/home/todd/.bin/bandwidth-test: line 21: [: : integer expression expected
BW Surchargé - Moyenne de de Kb/sec pendant 20 secondes
This is the script:
#!/bin/bash
# bandwidth-test - test bandwidth from the command line
Fic_Tmp="/tmp/Fic_Tmp_VerifRatio.tmp"
NbrSec=20
/usr/bin/bwm-ng -I eth0 -o csv -T avg -C " " -c ${NbrSec} | awk '
BEGIN{
BytesS=0
NbrLecture=0}
/eth0/&&NR>2{
BytesS+=$5/1024
NbrLecture+=1}
END{
Ratio=BytesS/NbrLecture
printf ("%4.0f", Ratio)}' > ${Fic_Tmp}
Ratio=$(cat ${Fic_Tmp})
rm ${Fic_Tmp}
if [ "${Ratio}" -lt 110 ];then
echo "BW OK - Moyenne de ${Ratio} de Kb/sec pendant ${NbrSec} secondes"
exit 0
else
echo "BW Surchargé - Moyenne de ${Ratio} de Kb/sec pendant ${NbrSec} secondes"
exit 2
fi
exit $?
Anyone available to fix this for me?

Answer 1

Ah, thought I counted all those.  Whoops .  Yep that did the trick.  Thanks benob.
Edit: Just FYI to any that read this.  This script only checks if you are in the cap range, so it's not really a bandwidth tester for the command line.  The nearest I've found is 'iperf' which I'm unable to get to use yet.
Edit2 : netperf seems better suited for this, only been able to learn how to do download speed test so far:
netperf -c hostname -f K
