And...

do you have a question?

Normally a link will be from the Primary Key (a unique, preferably meaningless
numeric identifier) in the "one" side table to a field of the same datatype
(Number, Long Integer if the primary key is an Autonumber) in the child table.
Since nobody here has any way to tell what a "unit" or a "name" is in your
system, nor the meaning of anything in your tables, it's more than a bit hard
to say!

I would recommend that you do NOT use special characters (blank, #) in
fieldnames, and that you also do not use reserved words such as Name.

You might want to read some of the tutorials in these links - Crystal has a
good chapter on Normalization which might help.
