Import Spreadsheet Error

Using an access project front-end to an MSDE database, I'm trying to
import a spreadsheet using File->Get External Data->Import.
After I select the spreadsheet name, I tell it I want to import into an
existing table and select the table name from the list. The name in
the list is dbo.Cost_Data. When I tell it to finish, it says the table
does not exist.
If I do the same steps as the database owner, the table name does not
contain the "dbo." on the front of it and it is successful.

Thanks for any help.
