Awk script problem

[angermanaged]

I have been writing an awk script to calculate and report on sales numbers for a couple different files. The only problem i am having is when i try to call the script.
I want to invoke the script by way of

awk -f report products associates sales

But so far when ever I do that errors are produced such as:

awk: report:2: awk '/2008/{print $0}' sales > /tmp/newSales
awk: report:2:        ^ invalid char ' ' ' in expression

When I invoke the script with

./report products associates sales

It works perfectly

Can someone explain to me why this happens and how to go upon converting the file so it works.

Here is the script file

#! /bin/bash
awk '/2008/ {print $0}' sales > /tmp/newSales

declare -a names
declare -a totalsales
declare -a position

echo -e "Name:\tPosition:\tTotal Sales:"
ID=1
while [ $ID -le 6 ]
do
  awk /[2][$ID]$/ /tmp/newSales > /tmp/sales.2$ID
  let ID=$ID+1
done

GRANDTOTAL=0
ID=1
while [ $ID -le 6 ]
do
  while read line
  do
    PRODID=`echo $line|cut -d"," -f1`
    QUANT=`echo $line|cut -d"," -f2`
    PRICE=`awk /^$PRODID/ products|awk -F":" '{print $3}'`
    TOTAL=$(echo "scale=2; $PRICE*$QUANT" | bc)
    GRANDTOTAL=$(echo "scale=2; $GRANDTOTAL+$TOTAL" | bc)
done < "/tmp/sales.2$ID"

totalsales[$ID]=$GRANDTOTAL
NAMES[$ID]=`awk /^[2]"$ID"/ associates | awk -F"/" '{print $2}'`
position[$ID]=`awk /^[2]"$ID"/ associates | awk -F"/" '{print $4}'`

echo ${NAMES[$ID]}":"${position[$ID]}":"${totalsales[$ID]} >> /tmp/output.$$

GRANDTOTAL=0
let ID=$ID+1
done

sort -n /tmp/output.$$ | awk -F":" '{print $1 $2 $3}' #/tmp/output.$$

# removes all created files
rm /tmp/sales.2*
rm /tmp/newSales
rm /tmp/output.$$

Thank you all who try to help me
