Hello, Sorry if I'm missing the obvious (yes I'm a newbie) but I've got a simple little cgi script that works flawlessly from the command line but has problems working from the web. It is just supposed to load different background images on each visit. When I run it from the web the bg.cnt file with just counts from 0 to 3 doesn't get written to properly and ends up with nothing in it. The permissions seem ok, with rw-rw-rw on the counting file. Thanks for any help anyone can provide. 
#!/usr/bin/perl

open IN, "<bg.cnt" or die "can't open bg.cnt"; 
flock(IN,2); 
seek(IN,0,0); 
$cnt=<IN>;

close IN;

if ($cnt >= 3){
        $cnt = 0;
                }
else {
        $cnt = $cnt + 1;
     }

open OUT, ">bg.cnt" or die "can't open bg.cnt for writing";
flock (OUT, 2);
seek(OUT,0,2);

print OUT "$cnt \n";

close OUT;

@background=("corner.jgp","anduin.jpg","gandalf.jpg","ford.jpg");

print "Content-type: text/html\n\n";
print <<EndOfHTML;
<td background="images/$background[$cnt]">
EndOfHTML
