If this is happening at the Table level, it indicates that the Subdatasheet
Name property is incorrect, or pointing to something that is incorrect.

Open the table in design view.
Open the Properties box (View menu.)
Set the Subdatasheet Name property to: [None]

The plus sign will no longer appear, and the problem is gone.
Alternatively, you could set the Subdatasheet Name to the name of the
related table whose data you wish to see when you click the +.

the database I have created has tables with a subform. When I try to open
the plus sign on a particular it says,"this expression is typed
incorrectly,
or it is too complex to be evaluated." What could be the problem?
