in reply to Use of uninitialized value in addition

Before performing addition operation ,check whether that array index is having value or not using define function.

Your code,
for my $valNum (0 .. $total){ $mean += $value[$valNum]; }
Change the loop like the following,
for my $valNum (0 .. $total-1){ if(defined($value[$valNum])) { $mean += $value[$valNum]; } }
