UPDATE using MS Access2002

[Antonio Fernandez-Vicenti <afvaiv@xxxxxxxxxxxxxx>]

In a small PC project we are using MS Access 2002.
I have an Access table that is partially incorrect in a certain field 
values.
I'm trying to UPDATE it, using corrected values from a different but 
similar table.

Found in the Archives the following thread, and changed it to fit my needs.

UPDATE Table1 AS t1
 SET Vendido = (Select Vendido
                           from Table2 t2
                           Where t1.ID = t2.ID)
WHERE EXISTS (Select 1
                           from Table2 t2
                           Where t1.ID = t2.ID);

When I try to execute, Access gives me an error "La operacion debe usar 
una consulta actualizable"  (translate from Spanish, so may not be the 
exact english words, but... "Operation must use an updatable query"... ) 
where Help is of no joy...

Does anybody know if Access 2002 supports this kind of  <Update a table 
from another table> using EXISTS as suggested for a different case in 
the Archives?

Thanks,
