recordset is not updateable

[lynn atkinson]

I have a query which links course bookings, employee and
their post. If I add the contracts table (which eliminates
the need to input the postid in to the employee details),
the query becomes non updateable. Can anyone explaing why
this happens?

 

[gandalf]

can you post your query

do both tables have a primary key?
etc

somehow the records cannot be identified as unique.
