[AccessD] A little help, please

That certainly helps the programmer decide if something needed editing, but it does not solve the 
"bound to a FK" issue.  If the two tables have different data but the same values for a PK, AND you 
are binding the PK to an FK in the currently displayed table, then you have a problem.

I was assuming that one table was dynamic and the other was static - imported data or something like 
that.
