Perl quoting issue

Hello,
In a Perl CGI script, I have the following line that outputs a bit of HTML:

print "
blah blah…
<input type=“hidden” id=“review” name=“review” value="$review"
blah blah…

" ;
When I run this program, I get the following error in my server log file:

Global symbol “$review” requires explicit package name at /var/www/cgi-bin/submit.cgi line so and so…

But I have already declared the variable $review with a

my ($review) ;

much earlier in the program.

Could anyone advise me as to what is going wrong?
