I am using mod 2, to find if a row is odd or even, creating a key based on the content of a field in a flatfile... it works fine, but i always get masses of errors in apache log ( win32) saying: Use of uninitialized value in modulus (%) at C:/Apache Group/Apache2/cgi-bin/blah.cgi line 281. what is it trying to tell me please! - its works so what am i doing wrong! thanks very much! 

my %alphabet;
my $s;


code...


    foreach $record (@contents)  {
    
    @fields = split(/\|/,$record);

    $tidm=$fields[0];$tidm=~s/\s+$//g;
    $nice=$fields[1];$nice=~s/\s+$//g;
    $s = substr($nice,0,1);



open (DATA, ">> ./ATOZ/$s.shtml" );

if ($alphabet{$s} % 2) {

print DATA qq|<tr bgcolor="#FFFFFF"></TR>\n|;
} else {
print DATA qq|<tr bgcolor="#F8F8F8"></TR>\n|;
}
        
close DATA;
    
$alphabet{"$s"}++;

}
