Hi all, I'm have an array of arrays in which I am trying to find the number of indices for any of the referenced arrays(they should all be the same). This list of arrays if returned from a mysql query. If I do something like this: 
    foreach my $row (@$list) {
      print "$#{$row} <br>";
      .....
    }

it works. The problem is I need to have the given number before I enter a foreach loop. So I figured this would work. 

 my $dref = $@list;
 my $num = "$#{list}"

But it doesn't. This is for a cgi script, and adding those lines causes this to be printed in my error log: 
Can't use string ("8") as an ARRAY ref while "strict refs" in use at /
+usr/lib/perl5/5.6.1/whiteware.pm line 109.

I'm so confused after reading the perlref and perllol man pages. Can anyone please explain to me what's going on? Thanks, Elam
