Yeah I suppose it's easier when there is a visual So I have a spreadsheet that has 4 tabs. STATION1 thru STATION4. This first column in each tab is the rowId , just incremental row counter. data on STATION1 would look like this: 
1,,business,first,last,email,,,,,

STATION2(Column2 is a reference to Column1 in STATION1): 
1,1,,,123,Main,St,City,State,Zip

[download]
STATION3 (Column2 references Column1 in STATION2): 
1,1,1,P-550,11223344
2,1,2,P-330,22334455

I am inserting data into two hashes like so: 
$excel{$tab}{$row}{$col} = $cell->{Val};
$rehash{$tab}{$id}{$row} = $excel{$tab}{$row}{$col};

[download]
This attempt is finding no results: 
for my $s2_key (keys %{$rehash{"1"}}) {
                        if ( exists( $rehash{"1"}{$s2_key} )) {
                                print SOMETHING;
                        }

Update: Durrr! That's what I get for operating on no sleep. Put "1" instead of "STATION2". I will continue to fiddle.
