INNER JOINS

(OP)
I have a small Access data base with 5 tables.  Table 1 is OptSys and has the primary key, OptID.   Table 2 is a System Name table (SysTbl) with a SysID foreign key.  The other 3 tables have Location Codes and the SysID foreign key.  I need to create a query that will build an updateable recordset that will contain the OptName and corresponding System Name, and link the other 3 tables on SysID to get the 3 location codes, as well.  I have tried this :  

SELECT *
FROM OptSys INNER JOIN SysTbl INNER JOIN
LOC1Tbl INNER JOIN LOC2Tbl INNER JOIN LOC3Tbl
ON LOC2Tbl.SysID = LOC3Tbl.SysID
ON LOC1Tbl.SysID = LOC2Tbl.SysID
ON SysTbl.SysID = LOC1Tbl.SysID
ON OptSys.OptID = SysTbl.OptID;

But I get an error in the FROM Clause 3131.

I have also tried this:

SELECT *
FROM (([OptSys] INNER JOIN LOC1Tbl ON [OptSys].SysID = LOC1Tbl.SysID) INNER JOIN LOC2Tbl ON [OptSys].SysID = LOC2Tbl.SysID) INNER JOIN LOC3Tbl ON [OptSys].SysID = LOC3Tbl.SysID;

With OptSys being an initial query as:

SELECT OptTbl.COG, SysTbl.System, SysTbl.SysID
FROM OptTbl LEFT JOIN SysTbl ON OptTbl.OptID = SysTbl.OptID;

This produces the desired result, however the data is not updateable…..
