Linked - back end file

[Corleone]

I have a database which I have splitted

I can now no longer make any changes to the table as they are linked
I have tried making a change to a feild in the back end file but this does not cascade through into the main database file

Any ideas where I am going wrong?

If you're changing up your tables, you'd probably have to change the table in the back-end, delete the link in the front-end and create a new link to that same table. Seems like it would automate this task for back-end changes, but I guess it doesn't.
