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?
