[SLUG] Search and replace question

[Mehmet Yousouf]

Hi,
I'm having trouble with the following search and replace script:

#!/bin/bash
# two parameters are passed in, a mapping file and the text file to replace
in

for fields in $(cat ./Mapping/$1-Mapping |awk 'BEGIN{FS=","}{print $2}')
do
  searchstring= $fields
  replacestring="`grep -w $fields ./Mapping/$1-Mapping |awk
'BEGIN{FS=","}{print $1}'`"
  sed -e "s/$searchstring, / $replacestring, /g" $2 >TestResult
done 

 it fails if there is a $ sign in the variable $field e.g. amount_$ . How
can I get grep to "behave" the way I want?
Any help would be appreciated.

Regards, Mehmet
