Replication is actually not as difficult as the documentations might make it sound.
Basically, the simple way to accomplish what you want to di with replication is:
-- create a design master database by enabling your existing database for replication.
-- you will use the design master as your main database at your "home base"
-- create three replicas and install one on each of the three salesperson's laptops.
-- when the salespeople need to update the design master with changes, and get changes made to design master and other replicas, just put them on the network and choose the "synchronize" replica choice from the replication menu. Then specify which replica you want to synchronize and push the button. Changes from the salesperson's replica will be uploaded, and changes made on the design master (which may have come from other replicas) will also be downloaded the the syncrhonizing replica.
I was a little intimidated at first by descriptions of replication. But when you actually do it you will probably find out it's not as difficult or mysterious as it seems.
If you can't bring the salespersons' laptops on to the network to synchronize, then you can also do it fairly easily (depending on size of database and whether or not you have broadband connections) by having them email their current database in, doing the syncrhonization at the home base, and emailing back the new syncrhonized replica.
There are also ways to set up synchronization automatically over the internet, without having to email the .mdb file in, but that is more difficult to configure. -- Herb
