VLOOKUP with multiple criteria and multiple csv output - excel

Question

I have two tables:
Table-A
List of regions and road types for each name (used letters for example)
Area Road Type Name
Masterton, Carterton LR A
Wairarapa LR B
Hamilton, Cambridge SH C
Auckland, Christchurch, Wellington LR,S D
NI SH E
SI SH F
NZ SH,LR G
Kapati, Levin LR H
Manawatu LR I
Napier SH J
Hastings, Havelock North SH,LR K
Hawke's bay LR L
Dunedin SH M
Napier LR N
NI LR O
Table-B
List of towns, provinces and islands (NI = North Island, SI - South Island)
Town Province Island
Masterton Wairarapa NI
Carterton Wairarapa NI
Hamilton Waikato NI
Cambridge Waikato NI
Auckland Auckland NI
Christchurch Canterbury SI
Wellington Wellington NI
Kapati Kapati Coast NI
Levin Horowhenua  NI
Napier Hawke's Bay NI
Hastings Hawke's Bay NI
Havelock North Hawke's Bay NI
Dunedin Otago SI
When you enter a Town into C2; C5, C6, and C7 will Vlookup Table-B to get the relevant data.
That's the easy bit.
What I am trying to do now is to get a list of names from Table-A (separated with a semi-colon) where either the town, province or island (from the vlookups) exists the in Area column and the Road Type (entered in C3) exists in the Road Type column.
Based on the input above the result would be: N; L; O
Can't seem to find an example of a vlookup that would provide the output
Any help would be greatly appreciated.
UPDATE:
My boss has hopefully made the solution a little simpler. Instead of the two tables, he has provided a single matrix showing:
Email T1 T2 T3 T4 T5 T6 T7 LR SH
A X X X
B X X X X
C X X X X X
D X X X X
E X X X X
F X X X X X
The T# represent a territory the user is interested in and one or both of LR and SH. So if the user provides a T# and either LH or SH the lookup needs to pick the email addressed where there is an X in the relevant T# column and an X in either LR or SH.
So, based on the table above:
T3 and LR would result in C, F
T1 and SH would result in B, F
T6 and LR would result in C, D
Not sure if this simplifies the solution or not.

Answer 1

Assuming that Table A is located at A3:D18, Table B is located at F3:H16 and the input Town and Road Type and the related Province, Island and Names are located at J3:N29.
To obtain the corresponding Province and Island, enter this formula in L4 and M4 then copy downwards:
=VLOOKUP( $J19, $F$3:$H$16, MATCH( L$3, $F$3:$H$3, 0 ), 0 )
To obtain the Names for the corresponding Town, Province and Island in one cell separated by ;, Enter this Array Formula in N4 then copy downwards:
Array Formulas must be confirmed by holding down CTRL + SHIFT + ENTER
=CONCATENATE(
IFERROR( INDEX( $D$3:$D$18, AGGREGATE( 15, 6, ROW($D:$D) / ( ( $D$3:$D$18 <> "" )
* IFERROR( SEARCH( $J19, $B$3:$B$18 ) > 0, NA() )
* IFERROR( SEARCH( $K19, $C$3:$C$18 ) > 0, NA() ) ), 1 ) ),"N/A"), "; ",
IFERROR( INDEX( $D$3:$D$18, AGGREGATE( 15, 6, ROW($D:$D) / ( ( $D$3:$D$18 <> "" )
* IFERROR( SEARCH( $L19, $B$3:$B$18 ) > 0, NA() )
* IFERROR( SEARCH( $K19, $C$3:$C$18 ) > 0, NA() ) ), 1 ) ), "N/A" ), "; ",
IFERROR( INDEX( $D$3:$D$18, AGGREGATE( 15, 6, ROW($D:$D) / ( ( $D$3:$D$18 <> "" )
* IFERROR( SEARCH( $M19, $B$3:$B$18 ) > 0, NA() )
* IFERROR( SEARCH( $K19, $C$3:$C$18 ) > 0, NA() ) ), 1 ) ), "N/A" ) )
The formula above returns N/A when the combination of Road Type and Town, Province or Island is not present in Table A.
