NEW: need help with nawk using -v vars
I'm trying to pass nawk a shell variable to be used in a pattern match. I can't get this work.

I'm calling nawk from a /bin/sh

I want that when somebody enters Trunk Group in variable TGR so it goes into nawk variable TG.


Code:
echo "Enter TRUNK GROUP:"
read TGR

cat /omp-data/logs/5etr/$SearchDate.APX | nawk -F"|" -v P=$TGR '
#cat /omp-data/logs/5etr/$SearchDate.APX

BEGIN {

       TG=$P;

 printf ("DATE IN ST EN  TGN ISEIZE ISATMP   IANS OATMPT   OVFL OSEIZE OSATMP   OANS TOTUSG OOSMTCE   OOS DBLSZR NTWCONG\n");
}

PLEASE can anyone help me out with this code somehow it does not work..
THANKS in advance

Can you please tell me that do i have to convert variable P into integer in BEGIN. Because now it is running but giving no output.
Actaually value of P should be like 700, 701, 744, 601 like this..

echo "Enter TRUNK GROUP:"
read TGR

cat | nawk -F"|" -v P=$TGR '
BEGIN {
TG=P;
printf ("DATE IN ST EN TGN ISEIZE ISATMP IANS OATMPT OVFL OSEIZE OSATMP OANS TOTUSG OOSMTCE OOS DBLSZR NTWCONG\n");
}
. . . . .
' /omp-data/logs/5etr/$SearchDate.APX

I moved the input filename on the awk command, but i forgot to remove the cat command.
Code:
cat | nawk -F"|" -v P=$TGR '
