This is probably a very simple question, but it is annoying me.

Code fragment:

my $score=100000;
open (IN, $arq);
while (<IN>) {
     open (IN1, $_);
     while (<IN1>) {
         my @temp=split(/\t/);
         if ($temp[1]<$score) {

When executing this code, it complains "use of unitialized value $score in numeric lt...".

I cannot figure out why the variable, defined in the top most level of the program is not the same in the IF condition.

TIA
