Kinda embarrassed to post this, I'm very new to coding, it's bound to be trivial and you guys seem a little beyond that! But here goes:

I'm trying to validate input from a form field by testing if the value's not null (ie has that form field has been filled in). However, the array is refusing to see anything at all, ie treating a filled-in field as though it hasn't been filled in. But a variable seeing the same field *can* see what's there.

form code: 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html><head><title></title></head> 
<body> 
<FORM ACTION="tst.cgi" METHOD="post" ENCTYPE="multipart/form-data"> 
<INPUT TYPE="file" NAME="photo00"> 
<INPUT TYPE="submit" NAME="Submit" VALUE="Submit Form"> 
</FORM></body></html>

perl code: 

#!usr/bin/perl -t 
use strict; 
use warnings; 
use CGI; 
use CGI::Carp qw/fatalsToBrowser/; 
use File::Basename; 

our $query = CGI->new; 
our @array = (); 

our $photo = $query->param("photo00"); 

# check if the field's not null, if not, array it 
if ($photo != "") {push(@array, $photo);} 

print "Content-type: text/html\n\n"; 
print "@array \n"; # this does nothing - how come? 
print "$photo \n"; # this prints to screen fine

Many thanks, and a very Happy New Year to you all from Spain
