in thread comparing an ID fom one file to the records in the second file

Thankyou so much for the help poj. Much appreciated. and I understand the logic how to do this type of task i.e., using the hash and storing IDs as keys etc. But there still exists one problem. The code is not comparing the hash key (ID) with $col2 and is not printing the related line :(. I commented out the (print "$col2") and it is printing nothing. I am trying to figure this out in the mean time.

    Check that your ID file does not have hidden spaces, tabs etc. Ensure 'clean' data by adding a regex

    while (<FILEID>){
  chomp;
  s/[\s]//g;
  $ID{$_}=1 if $_;
}
