Table relationships and lookups

Hi guys, I may be a little over my head, I've had some experience in
creating simple access db's. however this one will be extremely
complicated as far as I can tell. Some backround info - i've got an
excel spreadsheet currently that i would like to convert to Access.
The spreadsheet does multiple lookups and calucations.

This is for a Soccer club that i run to maintain roster information,
dollars, scheduling and stats. I'm currently working on the
scheduling pience. Here's what I have so far.

tables.
Club - Lists the teams in the club, home field name and address, city,
state, zip and notes
Opponent - Lists the teams in the league, home field name and address,
city, state, zip and notes
League_division - Basic, lists the league divisions 1,2,3,4 ( I didn't
want to include this in the two previous tables because teams can move
up and down depending on the season records.
League_Season - Hopefully to use for keeping historical data, players
and game info.
Schedule - This is going to be for entering each shceduled game.

Schedule table includes the following fields
Game_ID - AutoNumber
Game_Date - Date of game
Game_Time - Time of game
Game_Location - Value list, Home, Away, Other
Game_ClubTeam - Combo box of Club team from Club Table
Game_Opponent - Combo box of Opponent team from Opponent Table
Game_FieldName -
Game_FieldAddress -
Game_FieldCity -
Game_FieldZip -
Game_FieldNotes -

What I would like see is this.. Once the Game_Location, Game_ClubTeam
and Game_OpponentTeam has been chosen, I would like the
Game_fieldName, Game_FieldAddress, Game_fieldcity, Game_fieldState,
Game_fieldZip and Game_fieldNotes all be filled in automatically based
on the Location, club and opponent fields.

I don't know if I am over complicating this, but I really don't know
where to start.

Both the ClubTeam and OpponentTeam Tables have matching fields.

Anyhelp would be greatly appreciated.

Thanks!
Shaun
