Thanks I've solved in this way. The field "CostoEffettivo" is used in
the form only to do a calcul in VBA, I only had to place a Val() in that
piece of code.

Some note about the very stupid behaviour of Access. When I link an ODBC
table, if it has not a unique identifier such a primary key, Access asks
me for that. If I don't choose any field Access will refuse to make any
update or insert in the table. So, I think, if I choose the primary key
fields for the table, Access will use only that fields to do updates.
But, NO, Access will use practically all the fields of the table (really
not all the fields, don't know what criteria it uses to choose them), so
I ask: why it needs to know a unique identifier when it link tables? It
could simply use *always* all the fields of the table as unique identifier!

Anyway, thanks a lot for your answers.
