Could please tell were to specifically put the could you gave. I have no idea where to put the code.

Code:
compfile=~/sample_data.txt
clear
bold=`tput smso`
offbold=`tput rmso`
echo $bold
tput cup 3 1; echo "UsedComputersRUs Menu- Search Computer"
echo $offbold
tput cup 4 1; echo "======================================"
tput cup 5 1
echo "Enter computer to search for: "
tput cup 5 31
read compdate
echo
grep -i $compnumber $compdate $model $manufacturer $price $compfile
if [ $? -eq 1 ]
then
echo "No Matching Records Found"
fi
echo 
echo "Press ENTER to continue..."
read continue

It was pretty clear from vgersh99's post where to place his solution.

Anyway, here it is.

Code:
#! /bin/ksh
compfile=~/sample_data.txt
.
.
read compdate
echo

exec 3>&1
eval $(exec 4>&1 >&3 3>&-
  {
   grep -i $compnumber $compdate $model $manufacturer $price $compfile 2>&1 4&-; echo "exitCode=$?"; >&4
   } | tr ':' ' '
);

if [ ${exitCode} -eq 1 ]
then
echo "No Matching Records Found"
fi
echo "Press ENTER to continue..."

read continue

I get same error. That is way asked where to place the new code. I was testing it before an I keep on getting the same error. I don't understand what the error message states.
