GAH! Bash script insanity

Ok, I'm going crazy. I don't know how the script-kiddies deal with bash.
So the advice I got from the list re: my awk problem was great, and I'm
trying to implement it. Here is what I want to run:
sed -e s/#.*// ${CONFIG_FILE} | awk -F"=" '/${PARAMETER}/ { print $2 }'
The insanity comes from finding the right combination of "s, 's, and `s
so that $CONFIG_FILE and $PARAMETER are interpreted by the bash script
interpreter, while $2 is NOT, and is passed to awk, while
simultaneously keeping the sed and awk commands separate from each
other (apparently if you try things like:
` '<above string' `
the interpreter passes the | to sed as an argument rather than breaking
the commands up.
I guess I want something like:
RESULT=`sed -e s/#.*// ${CONFIG_FILE}` | `awk -F"=" '/${PARAMETER}/ {
print $2 }' `
But I can't quite get it. Its driving me MAD.
Any ideas, besides shooting myself and re-writing this in C or
hardcoding everything?
