Do you have warnings and strict enabled? 



       $id = getParent ($taxId);

The variable $taxId is not available inside this subroutine so it's the same as saying: 

       $id = getParent (undef);

     while ($taxId = $taxId1){
        my $parent = `getz "[taxonomy:$taxId1]" -f pid`;

The variable $taxId1 is not assigned a value until later in the subroutine and is not defined at all.
