Both above scripts work for me, I think the problem lies elsewhere.  '' 
quotes mean literal, so no expansion of variables is done.  Quotes 
inside of quotes are just characters, only the outer most count (AFAIK).

VAR=test

echo '$VAR'    prints: $VAR
echo "$VAR"    prints: test
echo '"$VAR"'  prints: "$VAR"
echo "'$VAR'"  prints: 'test'

If that helps at all.  You might want to try sticking with only " and 
escaping the ones inside:

echo "\"$VAR\""  prints: "test"
