If you really are comparing a string ... then use the string comparison operator: 

if ($lineData[18] eq $date) {

[download]
You additionally should place a temporary "debug check" to see what is really going on: 
warn "comparing $lineData[18] to $date\n";

if ($lineData[18] eq $date) {

I'll let someone else comment about about $lineData[18] itself.

UPDATE: Here is a little test for you: 

no warnings;
print '12/Mar/2004' eq '12/Mar/2004' ? 1 : 0;   should be 1
print '12/Mar/2004' == '12/Mar/2004' ? 1 : 0;   ????

print '31/Mar/2004' eq '12/Mar/2004' ? 1 : 0;   should be 0
print '31/Mar/2004' == '12/Mar/2004' ? 1 : 0;   ????

__END__

I'll bet you didn't turn warnings on, did you. :)
