Update Query to transfer data from one table to another.

I have a database which runs offline, no network
connection.
I need to udate a column with the current employee badge
number right before I take it offline.

So Local table has columns like:
Empl# Badge# info1 info2 info3 info4

The network table has:
Empl# Badge# LName FName

So I want to run and update query that will update all of
the Local table Badge#s based on the Empl# being equal.

Any help would greatly be appreciated.

Thanks

A simple JOIN will work here, if Empl# has a unique Index (it should!)

Create a query joining the two tables by Empl#. Change it to an Update
query; update Local.[Badge#] to

=[network table].[Badge#]

The brackets are required.
 
I guess I should've given my error, but I just thought
maybe I was doing it wrong...
When I put this in I get

"Operation Must Use An Updateable Query"

If I remove the join and do a simple update comment feild
to hi where empl# = 5 it works fine, so I assumed it
must've been the join that screwed me up.

Update Local INNER JOIN Remote ON Local.[Employee Number]
= Remote.EMPLOYNUM set Local.badge = remote.badgeid

After looking up the error I think my problem may be that
there are multiple rows in the Local table with the same
employee number.

Can an update be done on a many-to-one join?
 
I must be stewnad....
I didn't have any primary key on the local table, and
there was no unique identifier.....
I added an index column as autonum and it operates as one
would expect....
thanks
